Details & Assessments Individual assignment details are posted at the above link Assignments with scores 9 and above are recommended for reading by all. A1 marks Assignment 2 question: Design a Turing Machine to find the 10's complement of a 7 digit decimal positive integer. The original positive integer may have some leading zeros if necessary. The result also should be of exactly 7 digits. Keep the answer ready with you. Send it along with the answer to the question which will posted on 19/1. Don't send anything before that. 18/1: Practice to explain the way the TM works for a particular input, and also to write the ID sequence for it. A2 marks
Attendance	Students are expected to attend all the classes. Please be at the class at the time of commencement. Attendance shall be marked only if physically attend the class. As per KTU rules, absence for all activities and contingencies should be limited to 25%. Also, duty leave if any, will not imply presence or attendance. And, late comers will be marked, and two late marks will count as one absence. In the absence column below, prefix CHN18CS is omitted. Attendance count up to 30/10 is here. Those below 22.5 = 75% please take note. Such cases are reported to higher authorities as required.

/Announcements/Information

5/3/21

The university exam QP seems very good on first look. If you have any concerns about the questions please inform me. I will be conveying my comments about the QP and answer key to the university may be on Monday.

Meanwhile, on 25/2 I have received a copy of the complaint sent by one of the students from one source. May be from other sources on the pipeline. Okay, that is your right to raise grievances.

20/2

In all the retest and attendance discussions and decisions until yesterday I was also a party.
But, the following change of attendance is solely as per the direction of institution authorities today.

Change of attendance:
006 75%
052 75%
075 75%
117 75%

The attendance was published on 6/1/21, more than 40 days ago. So, why are you coming with claims so late?

Day's on-camera retest: "After every page is completed it should be shown on the camera". Checked the video. I could not see this action. Moreover Arjun's video was offline many times.
What do you both have to say?

Retest result (50)

As per the discussion with HoD and staff advisor it is decided to add this marks out of 50 as such to the existing sessional and if they reach 19 marks, it will be adjusted to 22.5. That in effect is the score out of 150!
050 will retain what he gets based on the computation with the re-test mark as his T1 mark. Computed it as 24.
Unfortunately, some students who could not make it to reach 19 marks have to undergo the option available as per KTU regulations.

Those who scored high marks should score well in university exam to retain it. Else by normalisation rule sessional will be scaled down as per the formula used by the university.

Regarding attendance:
University's concept of attendance is to ensure that a student learn the subject by attending the class regularly. It is not a technicality issue. That is why the 75% stipulation. Of course you can make your own sarcastic comments about it. Even when you had to skip classes for supplementary exams, that itself will not create any problem. In addition some of you missed additional classes. Hence the shortage. Anyway, supplementary exam absence is to be within the 25% allowance or not is a contentious issue at least for the time being. Hence we will take a stance in favour of the affected students. Hence whatever docs which helps to decide your absence is to attend a university exam, will be considered. Only docs submitted so far. Will update after the verification.

118: 3 hours. Exam. Cleared. But what about other 14 absences?
104: 5 hours. Said to be N/w issue. Cleared. But what about other 14 absences?
006: 4 hours for exam absence will be counted. Rest of the absence, not considered.
044: 1 hour. exam. cleared.

18/2

Sessionals and attendance as uploaded at KTU are here.

C Batch

D Batch

Inform me if it is not as per published marks. Attendance, if above 75% actual value doesn't matter.

Re-test valuation is pending. Uploaded marks will be modified accordingly, and will be updated here.

Two students didn't attend the retest, requesting for online option. They didn't mention anything during the meeting session.
Anyway, they are offered an on-camera online session tomorrow. They have to arrange a quality audio-video facility in a clean clear room. The link will be provided, and the session will be monitored and recorded.
Camera and microphone should be ON throughout. Five sheets of paper and pen should be readied beforehand. The papers should be shown before the camera. After every page is completed it should be shown on the camera. Your movement should be visible throughout. Three minutes will be provided for printing or noting down the questions. After that the laptop or phone cannot be used, for that it should be kept a little away, but camera and mic should be active. If willing, reply me by email. And make arrangements, and I have to verify it before the test. Once the test is over, scan and upload them in front of the camera. The pages will be verified against the pages shown before the camera already.

Attendance shortage - KTU exam related claims: I want proof that you attended the examination on that particular day, hall ticket or registration details will not do. Also, I have to ensure that this is in addition to the 25% allowance already permitted - that I will do on my own.

058, 048 -- will be updated

9/2/21

121:T1: Re-valued: 11 0, 12 0, 5 0, 6 0, 7 0, 12 0

6/2/21

https://meet.google.com/pzr-uuwg-eog

Highlights of discussion:
121: T1: Qns to be answered were computed wrongly. Discussed way back in October. Will check and update today.
083: A1: Says n/w issue at J&K. Didn't see A1 question! Should have been completed by October 8! Anyway, will evaluate the submission of 4/2/21.
104: Attendance: Says due to BSNL n/w issue during 18/12 - 2/1/21. Asked how to verify? Not easy. Asked to represent via staff advisor and HoD.
126: A2: Late. Want to reconsider, quarantine and n/w issue, which could have been reported in advance. Answer checked. There is no scope to award more marks as per the answers.
050: Retest reminder. His concern is genuine.
058: A2, T2: Want to check. Done.
110: Want general retest for T2. Think of on-campus option and request at the class committee meeting later today. (No rep requested retest there)
071: A2: Rejected due to very delayed submission. Personal (funeral related). Why matter was not raised before? Asked to request through staff advisor and HoD. No commitment yet.

121: T1: Request accepted. Qs to be answered. 1 4 5 8 9 12. Your Computed values - 6 7 5 11 12 15. Of (5,6) and (11,12) only one each could be considered as they are identical. There is no Q15. So 3 Qs 5/6, 7, 11/12 will be valued. Will refer the valuation doc kept at college on 8th or 9th to decide the marks to be awarded.

5/2/21

Plan to be online tomorrow 10.30AM

4/2/21

"In C batch there are 7 students who have not got the minimum marks in the internals. Sir what is the next procedure for us to pass the internals. On behalf of all I request you to do the needful for us."

Above is the content of an email received by me on 2/2/21.
There is no immediate solution at my disposal. Sessional marks are assessed by continuous evaluation. Reiterating, it is a continuous evaluation process. I hope I have done it via two tests and two assignments spread over the entire semester. Now, my work is over. There is no common solution for those who failed to make use the opportunity before them for the entire semester.

But, individual cases like feeling that didn't get the deserving marks in tests or assignments due to evaluation errors or any such matters I am willing to address.

I cannot offer a simple on the spot solution for the problem created by not seriously participating in the academic work for an entire semester. Genuine cases if any will be addressed individually. Shooting an email without convincing information will not do.

Attendance also I have finalised on my part.

No case detected with a1 or a2=0 and total sessional > 45. So ceiling not applicable.
T2: 49,59,15,48 are seen having zero marks. They all are verified to have attended T2 and submitted their files in time with correct file names. So 0.5 will be their minimum marks. Updated.

30/1

Retest for 050 will be announced later, probably on 2/2/21

29/1

The published provisional sessional is based on the assumption that the student had submitted both the assignments and written both the tests. If not, corresponding ceiling will be applied.
And also, there are some suspicious similarity of answers noted down against T1. The decision on those cases may be applied on the sessional.

Attendance shortage list published on 6/1/21 is still valid

For the retest for 050 the questions will be from the first four modules. Probably tomorrow morning.

Corrected:
085: Missing A2 entry corrected.
058: A2 Wrong penalty rectified.

https://meet.google.com/pzr-uuwg-eog

Internals are ready. See above table

27/1

A2 marks are ready:
Breakup:
(1) Complete definition of the TM to compute the 10's complement of a 7 digit decimal number - 7 tuple definition for this problem (for any 7 digit number) - leading zeros cannot be ignored (2 marks)
(If leading zeros are ignored - 1 mark)

(2) Explain how the TM behaves on processing your input until the final result is generated: Your specific input based: 4 marks(For descriptions based on correct TM design)
For descriptions based on incorrect TM design - max 3 marks

(3) Write down the ID sequences as discussed in class for your input: Proper formal ID sequence 4 marks(For IDs based on correct TM design)
For IDs based on incorrect TM design - max 3 marks

Please check your marks and be ready to present your case if have claims for more marks. Please don't hesitate. But, be prepared with clarity of arguments. I will listen you tomorrow 11 AM.

T2 pending cases also could be presented after A2 discussions.

From this score 1 mark for 'late', 2 marks for 'morelate', and 3 marks for 'verylate' will deducted.

21/1

For part (1) - Only the definition was asked. Explanation was not required. Of course the definition include the transition function represented either as a figure or as a table.
Also, there is no point is detailing what is 9's complement, 10's complement, how are they computed etc. That is elementary stuff at this stage of your career. Our focus was on the TM.

TM definition means: Define it formally for the given case using 7-tuple format, not the generalised definition.
Since it is given that the number is 7 digit fixed complement of leading zeros are also to be included. Argument that leading zeros are to be ignored is wrong.

19/1

Assignment 2 based question will be posted at 4PM today.

Be ready with neatly written design of the TM with complete definition.

Assignment 2 tasks:

Any one of our class could join to raise their concerns or to listen.

Some joined after 10 minutes. Only 009 raised an issue.

Observed extra entry in 072. Will be re-evaluated.

072, 009 corrected.

23/12

T2: 050 missing mark entries added.
I have some inconvenience at 3PM for the scheduled meeting.
Shall inform when ready.

Remaining assignments are posted.

T2: Late submitted marks - right and wrong file names together - provisional.
Subject to verification of undue advantage.

22/12

T2 marks of students received in time with correct file names - provisional.
Qn number and marks are written one by one horizontally.
071 072 mix-up rectified.

Q5: Answers of many are worth some consideration. But, due to similarity of answers, that was not applied. If you still feel otherwise claim it, if you have no shared answer in your answer paper.

T2 marks of students received in time with wrong file names - provisional

Will check other submissions case by case.

Simply sending emails to reevaluate some answers will not be heeded as it is impractical and also because I have already evaluated them. But, still to err is humane. Hence will look into genuine cases. Even though I don't have a history of committing too many such errors. Yet open. But, it will be your turn to convince me. So, ready with your arguments. We will discuss. One sitting will be at 3PM tomorrow. Any one of our class could join.

Question paper will only be available here.
Series 2 Question Paper

All files received in time (91) are moved to another folder.

The 10.30 regular class session stands cancelled.

Moodle test link is not active. Need not upload there now.

T2: Some immediate reactions.
-- So many late submissions. Not happy with that.
-- Many of you seems to have sent the answer papers to HoD and class group ids also. Unnecessary.
-- Even after repeatedly warning against it, many seems to have selected specific fixed sized strings for the pumping portions of pumping lemma. Wrong. As mentioned already, use YouTube sensibly. Also, don't blindly rely on substandard books.

10/12

Shall commence at 10.40, hopefully.

Session over.
N/w issues.

Sorry once again for forcing you to some futile time.

Meanwhile, no class notes assignment today.

Exam related:
The second series test will be from 8.30 to 10AM on December 11, 2020
Questions will be available here as well as at Moodle page from 8.25AM.
Send the answers by email latest by 10.15. I will be evaluating the email copies.
File name format: t2.chn18csxxx.pdf
Email subject: CS301 T2 xxx
xxx - last three digits of your reg number

Late receipts will not be evaluated. Google drive links will be silently rejected.
Upload to Moodle also.

Note that exam time is till 10AM. Hence 10.15 deadline for email receipt will not be relaxed.

As usual, write your own answer. You can refer online material posted by anybody before the commencement of the exam, and books, or notes.

I hope you will not share or discuss questions or answers during exam with others.
If ascertained/detected otherwise, will be treated very seriously.

There will be 7 questions. No choice. No subquestions.
They are from PL RL, PL CFL, CNF, CFG, Derivation tree, TM, and PDA.
Remember to read the instructions before the questions.

I will be online from 8.25 to 9 at https://meet.google.com/pzr-uuwg-eog

9/12

Too exhausted due to election duty to conduct the class at 10.30 .
But, wait!
Will have our session at 4PM today!!

Really sorry. Have been trying for quite some time to organize the docs for the lecture. But could not finish in time, on account of various reasons including server power stability issues. Hence no session today. Hope to meet tomorrow 10.30.

Hope to have a better experience tomorrow.

I have this plan. Let us see whether its works out or not.
The students are divided into 7 groups of 19 each.
One group each on each day will join the class via Jitsi meet.
The rest will join via YouTube channel, live streaming will be available, hopefully.
The one who gets class note assignment for the day can join via either of the options.
As usual type in your attendance via comment/chat.
YouTube may not permit comment via our college account.
Hence recommended to use your general google account for youtube access!
We will see how things go!

Moore and Mealy machine - Error in slide definition. Corrected and posted.
Start state is a member of set of states, and not alphabet.
All submitted assignments have been evaluated, remind me else.

Regular expression Kleene Closure operator^*is to be written as a superscript. (0+1)^* 0(0+1)^*.
Many of you have failed to write it that way in T1 - why?

T1: Somebody have even answered 10 or more questions. How is it possible in 90 minutes? I could see so many traces of unacceptable practices in answer writing. I can't address everything. But, definitely I am bound to address some of them.

11/10

Assignments received with correct file names are posted in the site mostly immediately. Marks remarks are posted when I evaluate it. Presently I am evaluating the test answer papers. In any case, the rest of the assignments received will be assessed on Monday or Tuesday.
T1: Who has solved Q6 first?!

1 0/10

Wrong answers shared are more easily detected.
Even though not required, why so many of you have shown the transition to dead state for questions 1 and 2?

Time slots for the remaining two classes this week:

9/10 2PM

Answer paper submission:
I have not commenced the processing. Will commence today one by one. I will be primarily depending on email contents. If submitted very late, what shall we do? - have to decide. Remember to have come across some cases where link to google drive file is submitted. Unfortunately I am not inclined to accept them prima facie.

Down loaded the files from mailbox. Not all seems to have followed the file name specification instruction. Think of the faculty who have to deal with 135 or so answer papers. Learn to abide the file name specifications. It is well within our domain. If you can't follow it, you need to learn it. Creating files with given name is elementary task for a CS student.

--------------------
Technically speaking in an automated system the files with wrong names may get rejected. Now you are putting extra burden on me to identify and process the files. I am giving these feed-backs to help you to learn.

Some emails I am receiving based on the above post. Even if with wrong name, if files are there they will be considered. Please don't send again.
In case of Anjana and Sreejith, you sent me links instead of files. My code didn't accept it. See my message already posted. Shall check Moodle.

Question Paper

Decide your questions:
Let R be the last three digit portion of your KTU register number + 316 (eg: 021 +316=337)
S=R*R (eg. 337*337=113569)
d1=first digit of S (eg. 1)
d2=second digit of S (eg. 1)
d3=third digit of S (eg. 3)
d4=fourth digit of S (eg. 5)
d5=fifth digit of S (eg. 6)
d6=last digit of S (eg. 9)
q1=(d1+d2)%2+1 (eg. 0+1=1)
q2=d2%2+3 (eg. 1+3=4)
q3=d3%2+5 (eg. 1+5=6)
q4=d4%2+7 (eg. 1+7=8)
q5=d5%2+9 (eg. 0+9=9)
q6=d6%2+11 (eg. 1+11=12)
Generate above numbers. Then answer questions numbered equal to q1 to q6. (eg. 1,4,6,8,9,12)
Then answer one of the questions numbered 13 or 14.

Send your answer paper copy from cec email id only.

Day's class session will commence at 10.45 via above link.

Exam related:
Upload file name: KTUID-subject code.pdf - in small letters, no space char in file name. eg. chn18cs001-cs301.pdf
My email id is: ask@ceconline.edu
Google meet link, in case of need during exam: https://meet.google.com/eby-kqcn-nvi
Write page number, ktu id, and name in every page as directed from college. Make a few pages ready beforehand.
Instructions on calculating your question numbers will be posted at 8.20AM here, and question paper will be available from 8.25AM.
Finish answer writing by 10AM and scan and send immediately, in any case before 10.15.
Our class session will commence at 10.45.

3/10

For the test, the question paper will have 14 questions, from which you have to answer 7. To determine which questions are to be answered, do the calculations given in the question paper very carefully. Do it first before attempting any question.
The question paper will be posted here, at Moodle, and also may be sent to you via email from college.
I will be online via the previous class link throughout the exam time, immediately after a scheduled meeting at 8.20 with exam cell. Queries if any will be replied to the extend possible via audio, chat, or email.
Follow other instructions including file name specification. File name is case sensitive. Do not insert extra space in file names.

The question paper will have some CO statements and question - CO mapping. Ignore those during the exam time. Ponder about them later!

2/10

For the series test most of the questions will be asking you to apply your knowledge. It will not be memory testing. We have learned some theorems. But none of them will be asked directly. May have to apply the theorems on problems.

Depending on your register number, questions and question details may vary from student to student.
Hope you all shall adhere to highest ethical practice. The probability of two students' answers are similar is very low. So, I may be forced to investigate if very similar answers are observed.

I am not expecting lengthy answers. Write precise answers focusing on what's being asked for( precise doesn't mean short though ). If asked to design an FA, provide the complete definition of the FA you are creating - and not the formal general definition. If only transition diagram is asked, do that only.

Further details later today or tomorrow. Read and understand the concepts well, that will help you.
All the best! Take it easy!!

Our session today will be at 11.30. It will be with new meeting code, which will be posted later.

Sorry for the failed session.

For tomorrow, identified another lab which when tested today lasted 6 hours uninterrupted. Let us pray and hope it will be smooth tomorrow!
Next week will be operating from home.

Meanwhile, those who got low scores in A1 need not worry unduly. If they perform better in the remaining evaluations, this deficit will mostly be wiped out.
But others, try to score as much as possible.

23/9

Operating from CEC this week.
Hope to be smooth!

While writing class note assignments, reproducing the slides alone will not be sufficient. You have to add statements corresponding to the explanations also.

13/9

This week I shall be operating from home. Arrangements are functional as usual. Some switching in case of power or net failures are the possible delays.
Hope to resume the classes at 10.30, 14/9/20

9/9

No class today also, as arrangements at CEC is not yet ready for me!

Chat in your ktu reg no. on joining.

For the third day in succession, the session got broken in between. Sorry about it. Shall address the matter.

Please, follow the instructions - especially with regards to email subject line.

R Aravind points out that the roll numbers posted by me are incorrect. It is what I got from official channel!
Anyway, since it is in doubt, we shall use the ktu reg number for the time being.

Observed that only 73 students have typed in their reg nos. via chat.
Next class onward everybody is requested to comply, else it will not be possible to record your attendance.

Sorry for the trouble.
Trying to figure out the participant limit issue, my system got unresponsive.
Will be back soon.

Rejoin at 9.30

We will try google meet.

Thank you for bearing the not so smooth morning session.
Sorry for the not so useful session.
Technical issues - Jitsi's participation limit, then hanging of my system, followed by network failure at my end contributed to the chaos.
Hope to have less of such issues next time.
I will be more prepared to address whatever I could foresee .

17/8/20

Tomorrow's sessions will be via Jitsi meet.
Network is okay at my end.
But, power interruptions may happen.
Otherwise, we hope to have some smooth sailing! - Everyday.
Come along!!

Details will be posted here.
