Please help with the following: Discuss the differences, strengths, and weaknesses in CISC Architecture and RISC Architecture.

How do you think multimedia is changing our lives? Where does it penetrates our daily living and is it a good or bad effect? What do you think will develop in the near and in the far future?

(a) Illustrate Amdahl's law in terms of speedup vs. sequential portion of program by showing the speedup for N = 8 processors when the sequential portion of the program grows from 1% to 25%. (b) ( Amdahl's law) With sequential execution occurring 15% of the time: (i) What is the maximum speed...

Summarize the significance of the halting problem in the field of theoretical computer science.

Write a Turing machine algorithm to perform a unary decrement. Assume that the input number may be 0, in which case a single 0 should be output on the tape to signify that the operation results in a negative number. When writing Turing machine algorithm, include comments for each instruction or r...

For questions 3 to 5, remember that a Turing machine starts in state 1, reading the leftmost nonblank cell. 1. Given the Turing machine instruction (1,1,0,2,L) and the configuration ... b 1 0 b ... (Tape read head is in state 1, and is over symbol 1 on the left) Draw the n...

Often there is a discussion on which comes first: Hardware or Software? Which is more important, or is it that both are equally important? Discuss.

Consider the following Turing-machine model (which is used in one of the standard textbooks in recursion theory, a branch of mathematical logic: Recursively Enumerable Sets and Degrees, by Robert I. Soare, Springer-Verlag, New York, 1987): The Turing machine is equipped with the following: (i)...

Please see the attached file for the fully formatted problems. (a) We wish to design a Turing machine which, using monadic notation, inputs a pair (in, n) of positive integers in standard starting position (on an otherwise blank tape), and which halts scanning the rightmost of a string of in is ...

Let A be a turing-recognizable language consisting of descriptions of Turing machines, {M1, M2,...}, where every Mi is a decider. Prove that some decidable language D is not decided by any decider Mi whose description appears in A. (Hint: You may find it helpful to co...

Let B be a probabilistic polynomial time Turing machine and let C be a language where, for some fixed 0 < 1 < 2 < 1, a. w  C implies Pr [B accepts w]  1, and b. w  C implies Pr [B accepts w]  2. Show that C  BPP. HINT: ...

Let  be a 3cnf-formula. An  assignment to the variables of  is one where each clause contains two literals with unequal truth values. In other words an  -assignment satisfies  without assigning three true literals in any clause. a. Show that the negation ...

Recall that NPSAT is the class of languages that are recognized by nondeterministic polynomial time Turing machines with an oracle for the satisfiability problem. Show that NPSAT = 2P. See attached file for full problem description.

Consider the problem of testing whether a Turing machine M on an input w ever attempts to move its head left when its head is on the left-most tape cell. Formulate this problem as a language and show that it is undecidable.

Let A = (attached) R and S are regular expressions and L(R)  L(S) . Show that A is decidable.

Show that the collection of Turing-recognizable languages is closed under the operations of a. union. b. concatenation. c. star. d. intersection

A Turing machine with doubly infinite tape is similar to an ordinary Turing machine except that its tape is infinite to the left as well as to the right. The tape is initially filled with blanks except for the portion that contains the input. Computation is defined as usual except that the head ne...

Give the transitions for a turing machine that accepts the language given below. L = {AnBnCn : n>=1} Where, An denotes a raised to the power n (a^n) Bn denotes b raised to the power n (b^n) Cn denotes c raised to the power n (c^n)

I have noticed that there are many languages, is this because no one language has all the major elements needed to be a perfect programming Language? What major features should a perfect programming language include? I am trying to understand the concepts and struggling.

Construct a turing machine to compute the product x*y of any two positive integers x and y. Assume that the inputs x and y are represented in unary and are separated by a single 0.

Give the transition list for a turing machine that will determine whether for an input sequence w over symbol set {0,1}, n0(w) = n1(w). n0(w) and n1(w) respectively indicate the count of 0s and 1s in the word 'w'.

Construct a turing machine that accepts the language {ww^R : w <- {a,b}+}, where w^R denotes w superscripted R - reverse of w. For example, if w = abb then w^R = bba ww^R = abbbba

Devise a Turing machine with input given in unary notation (i.e., a string of n 1's denotes the integer n, and numbers are delimited by 0's) such that the machine produces the following output: 0 if x is divisible by 4 1 if x is congruent to 1 modulo 4 2 if x is congruent to 2 modulo 4 3...
