In terms of regulated context-free grammars, the formal language theory has introduced a broad variety of leftmost derivation restrictions, many of which change their ...
- 《Theory Culture & Society》 被引量: 51发表: 2011年 Efficient Computation of Throughput Values of Context-Free Languages We give the first deterministic polynomial time algorithm that computes the throughput value of a given context-free language L. The language is given by a... D Caucal,...

Complexity of Suffix-Free Regular Languages A regular language is most complex in its class if it meets the quotient complexity (state complexity) bounds for boolean operations, product (concatenatio... J Brzozowski,M Szykuła - International Symposium on Fundamentals of Computation Theory 被引量...
An atom of a regular language L with n (left) quotients is a non-emptyintersection of uncomplemented or complemented quotients of L, where each ofthe n quo... J Brzozowski,H Tamm - International Conference on Developments in Language Theory 被引量: 41发表: 2011年 Combinatorial Complexity of...
Each step that results in a bit of information being "forgotten" by a computing device has an intrinsic energy cost. Although any Turing machine can be rewritten to be thermodynamically reversible without changing the recognized language, finite automata that are restricted to scan their input once...
2) most edited regular expressions have a syntactic distance of 4-6 characters from their predecessors, 3) over 50% of the edits in GitHub tend to expand the scope of regular expression, and 4) the number of features used indicates the regular expression language usage increases over time. ...
