 There are considerable and fundamental differences between Genetic Algorithms
and Simulated Annealing. GA is searching the whole of the search space and is
capable of finding non-obvious approximate optimums. While SA is a heuristic
Monte-Carlo based optimization.
 Which works best in practice for Chess Autotuning could depend on how close to
a 'real' understanding of practical chess evaluation we have in the chess
program at the moment of the test.
 A mainly linear formula should be easy for both GA and SA. While a discontinous
partially ordered set would probably favour GAs.
