Post subject: log(w/b) instead of w-b? Posted: Wed May 02, 2012 8:16 pm |

Inspired by Papa's entropy mobility evaluation, and recognizing that log(w/b) == -log(b/w), assuming floats, isn't the logarithm of a ratio (nominator, denominator > 0.0) in principle the "better" way, gaining more information than the plain usual difference in w/b, side2move related evaluation terms concerning material or mobility balance? Just curious. _________________ https://chessprogramming.wikispaces.com/ |
