Hello all, Someone made a benchmark on github to compare performance of different languages on a simple pathfinding problem:
https://github.com/logicchains/LPATHBench/blob/master/writeup.md It's getting popular and people are quoting the results they get from it to show that a language is really fast. Factor wasn't represented to I wrote an implementation of the algorithm here: https://github.com/bjourne/playground-factor/blob/master/lpath/lpath.factor Performance is pretty good I think. Factor runs in ~1340 ms while the Java version runs in ~1030 ms on my machine. And it wasn't that hard to get that speed -- you just replace safe generic words like nth with unsafe specialized ones like array-nth. Though I wonder if anyone has any ideas on how to make the Factor code run even faster? One idea I toyed with was making a non-recursive variant of the (longest-path) word. Right now it is co-recursive, (longest-path) calls ((longest-path)) which calls (longest-path). I think that if you can get rid of the co-recursion it would easily become as fast as the Java version. -- mvh/best regards Björn Lindqvist ------------------------------------------------------------------------------ New Year.
