Optimize benchmarks for http://benchmarksgame.alioth.debian.org/
Pick your favorite language and start optimizing.
Rules:Programs must produce the same results as reference and can be used for any data compatible with reference implementation(i.e. you cannot optimize for one set of data/variables).
Deadline:None.

You're no fun.
