Halting states are of two types. They are: a) Accept and Reject b) Reject and Allow c) Start and Reject d) None of the mentioned View Answer 3. WebGiven a language L and a nondeterministic finite automaton M, we consider whether we can determine efficiently (in the size of M) if M accepts at least one word in L, or infinitely many words.Given that M accepts at least one word in L, we consider how long the shortest word can be.The languages L that we examine include the palindromes, the non …

WebAug 18, 2024 · A PDA is non-deterministic. Nondeterministic automata accept a string w if any path along which w might be processed results in w's being accepted. so the PDA will try all paths and only accept the string if one of these paths landed in an accept state. Web1 Answer Sorted by: 3 You're right. This PDA will not accept 0 or 1 (or, more generally, any odd-length palindrome - do you see why?)

For example, if w = a b b, then w R = b b a. It is easy to see then that the strings of the form w w R are exactly the palindromes, such as a b b b b a.

WebPalindrome - Computation Theory Computation Theory In the automata theory, a set of all palindromes in a given alphabet is a typical example of a language that is context-free, but not regular. This means that it is, in theory, impossible for a computer with a finite amount of memory to reliably test for palindromes. textilbranche tarifvertrag

Since the PDA is deterministic, its computation is determined by its input. So we have to argue that the computation on x will not empty the stack. If it would empty the stack, then the PDA blocks, and can no longer continue.

WebThe non-deterministic pushdown automata is very much similar to NFA. We will discuss some CFGs which accepts NPDA. The CFG which accepts deterministic PDA accepts non-deterministic PDAs as well. Similarly, there are some CFGs which can be accepted only by NPDA and not by DPDA. Thus NPDA is more powerful than DPDA.
