    1. Show that the collection of Turning-recognizable language is closed under start , complement , intersection operation.
    2. Consider the sentence y x [R1 (x, x, y)]. Let’s assign PLUS to R1 where PLUS (a, b, c) is TRUE whenever a + b = c. If universe is N(Natural Numbers), is this sentence TRUE? Justify your answer.
    3. Show that set of all odd integers has one-to-one correspondence with set of even integer.
    4. Let B the set of all infinite sequence over {0,1} show B is uncountable using a proof by diagnolization.
    5. suppose there is a language L and we know that L is Turing recognizable. We can say L is also Turing Recognisable. Why or why not?

Mid Term Paper CS701 held on 29-05-2016
2 Qus 5 marks

2 Qus 10 marks

    Let LALL = {<M>|M is a TM with input alphabet Σ and L(M)=Σ*} prove
    that LALL is not Turing recognizable.

    If A<=B  & B is a regular language show that A is a regular language
    [001/01].[10/00].[01/011] in PCP problem. Find is there any match? If yes
    prove it.
    Let B the set of all infinitely sequence over{0,1}, show that B is uncountable using a proof by diagonalization.

An Other Paper same day

    [001/01].[10/00].[01/011] in PCP problem. Find is there any match? If yes
    prove it.
    In the silly Post Correspondence Problem, SPCP, in each pair the top
    string has the same length as the bottom string. Show that the SPCP is
    decidable.
    Odd integer has 1-1 correspondence to even integer
    ᗄy,ᣮx[Rz(x,x,y)] let assign plus to R2 where (a,b,c)is true where a+b=c if uviverse is Real number.

    My Questions:

    2 question 5 marks (each)

    2 Question 10 marks (each)

    Total 30 Marks

    (1) Can Turing Machines can perform 2 successive steps with moving it’s head? If yes explain. Also provide formal definition of Turing Machine. (5)

    (2) Check that X and Y are one-to-one or not. (5)

    (3) MORE = <A, B> are Turing machines Language of A is greater than B, is MORE <A, B> also decidable? explain for each case. (10)

    (4) show that some true statements in TH(N,+,X) are not provable (10)
