Slava Pestov	47fc3d87ad	RequirementMachine: Speed up PropertyMap lookups with a suffix trie ... Whereas term simplification uses a prefix trie with shortest matching, the PropertyMap uses a suffix trie with longest matching.	2021-08-06 14:17:20 -04:00
Slava Pestov	156fa2cc04	RequirementMachine: Speed up term simplification with a prefix trie ... Previously RewriteSystem::simplify() would attempt to apply every rewrite rule at every position in the original term, which was obviously a source of overhead. The trie itself is somewhat unoptimized; for example, with a bit of effort it could merge a node with its only child, if nodes stored a range of elements to compare rather than a single element.	2021-08-05 21:42:50 -04:00
