Show an Finite State Machine (deterministic or nondeterministic) that accepts L={ω∈a,b,c*: ω contains at least one substring that consists of three identical symbols in a row}. For example:
The following strings are in L:aabbb, baacccbbb.
The following strings are not in L: ε, aba, abababab, abcbcab.

Build a deterministic finite-state machine that accepts all bit strings in which the first and last bits are not the same, and that rejects all other bit strings. This problem requires at least five states. Here are three examples of strings that should be accepted: 01 0010011 11110 Here are three strings that should be rejected: 01010 1 11101

I need to construct a deterministic finite automata, DFA M, such that language of M, L(M), is the set of all strings over the alphabet {a,b} in which every substring of length four has at least one b. Note: every substring with length less than four is in this language. For example, aba is in L(M) because there are no substrings of at least 4 so every substring of at least 4 contains at least one b. abaaab is in...

Run JFlap, and use File->Open to open the problem1.jff file that we have given you. In problem1.jff, build a deterministic finite-state machine that accepts all bit strings containing at least three 1s and at most one 0, and that rejects all other bit strings. This problem requires at least nine states. You may use more states if necessary (there’s no penalty for doing so), but if you have time, try to get as close to the minimum as possible! Here...

For each of the languages below, draw the state diagram for a nondeterministic finite automaton (NFA) to accept the language. In order to get full marks, your NFA must have the number of states specified, and it must take advantage of nondeterminism. [There must be at least one case where the machine has a choice between two or more next states on some input symbol, or a case...
