DFA和NFA等价语言 、、 我被要求构建一个DFA A和NFAB,使得L(D) = L(N),并具有一些特定的条件。我不是在寻求解决方案或答案;我只是想确保我有正确的方法来解决这个问题。我正在考虑画一个符合这个条件的NFAB。然后使用这个图,我将构造一个等价的DFA A。有一个定理说等价的自动机具有相同的语言。所以我不需...

The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major ...
Visualize the Thompson-McNaughton-Yamada construction NFA for a given regular expression. The subset construction algorithm is also applied to the resultant NFA, resulting in a language-equivalent deterministic finite-state automata (DFA).Enter a regular expression: e.g. a*(b|cd)* ...
A nondeterministic finite automaton with ε-transitions(εNFA) accepts a regular language. Among the εNFA accepting a certain language some are more compact than others. This essay treats the problem of how to compactify a given εNFA by reducing the...

(dfa’s). We show that it is impossible to efficiently minimize a given nfa or regular expression withnstates, transitions, resp. symbols within the factoro(n), unlessP= PSPACE. Our inapproximability results for a given dfa withnstates are based on cryptographic assumptions and we show that...
One Cell BE processor can maintain NFA of 6000..7000 overall states simultaneously, so if one wants to use signatures with more that 512 states, it's possible with linear performance-to-signatures tradeoff. 展开 关键词: DFA NFA SIMD cell broadband engine network security regular expressions ...
The work process constitutes a reality in some sense superior to that of school, and this is why he so often longs to get to grips with it. Nothing done in school imposes its will in (28) the same way; if the maths is ill one can get on with something else. But even the boy ...
