[Info] Not so futile attempts

Title refers to an earlier post where I tried to add futility pruning in the past and never really got it to work.

This time though:

Rank Name              Elo    +    - games score draws
   1 Mediocre 1.0 -2    31   29   28   100   60%   31%
   2 Mediocre 1.0 -1   -31   28   29   100   41%   31%

So in worst case 2 elo better, in best case 60 (the -2 refers to futility pruning added to that version). But somewhere around 30 elo is probably accurate.

Combining this with the test last night would give this:

Rank Name              Elo    +    - games score draws
   1 Mediocre 1.0 -2    53   39   38   100   60%   31%
   2 Mediocre 1.0 -1   -11   12   12  1100   53%   24%
   3 Mediocre v0.34    -42   13   13  1000   46%   24%

Probably flawed to bits with no statistical significance. But I wonder if I can't say that Mediocre has gained somewhere upwards of almost 100 elo.

Probably not, but considerably better it is.

On to internal iterative deepening.
