A gate with three rotating arms at waist height is used to control access to a subway in New York city
Assignment involves solving problems by using various discrete techniques to model the problems at hand.
Let x be an element of S+ be a word. Show that for all such x, the language L=x* is regular. Give an example of x such that the language:
Discuss about a FSA (Finite State Acceptor) for all binary strings containing an odd number of 0's. A state diagram is the easiest for me to understand.
Prove that, if A is a regular language, a family of family programs B1, B2, ... exists wherein each Bn accepts exactly the strings in A of length n and is bound
Show the error in the following fallacious "proof" that P ?NP. Proof by contradiction. Assume that P = NP. Then SAT ? P. So, of some k, SAT ? TIME(nk).
A useless state in a pushdown automaton is never entered on any input string. Consider the problem of testing whether a pushdown automaton has any useless state
Show that the collection of decidable languages is closed under the operations of
Recall, in our discussion of the Church-Turing thesis, that we introduced the language D = {| p is a polynomial in several variables having an integral root}
Consider the language B = L (G), where G is the grammar given. The pumping lemma for context-free languages, Theorem states the existence
Say that string x is a prefix of string y if a string z exists where xz = y and that x is a proper prefix of y if in addition x ? y.
The language define by the equality of two 2DIM-DFA machines on all inputs is undecidable
Define two dimensional finite automaton (2DIM-DFA) is defined as follows. The input is an m X n rectangle, for any m, n X 2. The squares along the boundary
Write a grammar that generates the language described as the following set:
BNF is used extensively in the computing field to describe the syntax of programming languages. Please provide an example of where and how BNF might be used
Require assistance in describing in my own terms the difference between the extend and include relationships with an example
Design approaches used for business interfaces and those used for interfaces involving personal uses are the same. Do you agree with this statement?
The purpose of this 3 page paper is to describe how to improve persistence with Apache Derby and iBATIS
Using a simulator the boson simulator (or routers) I need to create a four router topology.
Noting Deadlock in a System.A system has 5 active processes(A-E) and one type of resource, which there are 200 total unites available
Recall that NPSAT is the class of languages that are recognized by nondeterministic polynomial time Turing machines with an oracle for the satisfiability
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.
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.
Give the transitions for a turing machine that accepts the language given below.
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
