we assign a minterm id to each of these classes (e.g., 1 for letters, 0 for non-letters), and then compute derivatives based on these ids instead of characters. this is a huge win for performance and results in an absolutely enormous compression of memory, especially with large character classes like \w for word-characters in unicode, which would otherwise require tens of thousands of transitions alone (there’s a LOT of dotted umlauted squiggly characters in unicode). we show this in numbers as well, on the word counting \b\w{12,}\b benchmark, RE# is over 7x faster than the second-best engine thanks to minterm compressionremark here i’d like to correct, the second place already uses minterm compression, the rest are far behind. the reason we’re 7x faster than the second place is in the \b lookarounds :^).

i haven’t found an implementation of the first one. the second targets javascript and should be available in node/chromium at some point. running /(a+)*b$/.test("aaaaaaaaaaaaaaaaaaaaaaaaaaaaaba") in my browser console still makes the fans spin for 10 seconds, so i’m fairly sure it hasn’t shipped yet. without implementations and benchmarks to compare against, i can only comment on the theoretical differences.。业内人士推荐同城约会作为进阶阅读
