A conservative extension to traditional nondeterministic finite automata (NFAs) is proposed to keep track of the positions in the input string for the last uses of selected transitions, by adding ...

If you stick to the concepts that I cover later, they will work across most flavors and Linux utilities. You don't need to think too hard about it. PCRE (Perl Compatible Regular Expressions) is the ...

There’s a Race to Power the Future. China Is Pulling Away. Beijing is selling clean energy to the world, Washington is pushing oil and gas. Both are driven by national security. By David Gelles ...

Computer animation researchers have been extensively investigating 3D facial-expression synthesis for decades. However, flexible, robust production of realistic 3D facial expressions is still ...

Quantitative aspects of systems like consumption of resources, output of goods, or reliability can be modeled by weighted automata. Recently, objectives like the average cost or the longtime peak ...

dregex is a Java library that implements a regular expression engine using deterministic finite automata (DFA). It supports some Perl-style features and yet retains linear matching time, and also ...

This is a C++ command-line tool that converts simplified regular expressions (REs) into deterministic finite automata (DFAs). It supports basic RE operators like: Kleene Star: * Union (OR): U Grouping ...
