Many engines/programs have different mappings, but a decent approximation of the cutoffs would be =>
0.30 maps to = (white's 1st move advantage)
0.60 maps to +/= : Slight advantage for white
0.90 maps to +/- : Clear advantage for white
1.30 and above maps to +- : White is winning
Depending on the engine's optimism, things could vary a lot as far +- (winning) evaluation scores.
Caveat : Remember => this is a computer's evaluation, not a human's. Try playing a frisky gambit and you'd think White/Black are winning on moves 2-3. :)
Could someone please explain how to determine a given numerical position score and its equivalent in symbolic terms?
Put another way, for each symbol evaluation of a position:
=, +/=, +/-, etc.
how does this translate into numerical positional score:
1.0, .58, etc.
Obviously a score of 0.0 would be an equal evaluation (=), but what are the parameters of the symbols and their numerical equivalent?
Thanks.
