This program a slight modification of MrBayes to do simulated annealing maximum likelihood tree searches (Bayes is credited with inventing Bayesian statistics, Fisher with inventing likelihood). I have a paper that describes it in prep, and I'm holding off on widespread distribution of the program until that paper's been peer-reviewed (since there may be comments that improve the paper). That said, the source is available on Google Code and a working citation for the program may be
