[Haskell-cafe] ANNOUNCE: GA-1.0, a library for working with genetic algorithms

2011-09-29 Thread Kenneth Hoste
Hello, I'm proud to announce the v1.0 release of GA [1], my library for working with genetic algorithms in Haskell. Source repo is available on github. [2] This is a major version bump compared to the previous v0.2 release, because the library is pretty mature now in my view. Major features:

p body is ridiculously small, so it would make sense to unroll it somewhat to help avoid the loop overhead. However, it seems like GHC isn't able to do that now. Is there any way to unroll the loop myself, to speed things up? Seems hard, because I'm using uvector... K. -- Ken
