Interesting diagram. I suppose the hc_0 and hc_1 prefixes mean the
inputs are for the player on roll and for the other respectively ?
The sum of the values seems to be about 0.5. Should the sum be 1 and the
basic inputs amount for the complement ? If this is the case, do you
have the actual sum for the listed inputs ?
PIPLOSS for one of the players is indeed at the top of the list, but
aggregated for both players MOBILITY seems to be about equal. The second
one, ENTER is interesting, it is 0 when the player doesn't have a man on
the bar so, when it matters, it may well be the most important input.
The first random ideas that come to mind :
- could it worthwile to add a few of the complex features like MOBILITY and
ENTER to the pruning nets ?
- the paper by Berliner mentionned by Ian in another follow-up describes
his efforts to improve PIPLOSS from a simple but not that good algorithm
to more or less what we have. Since, according to your analysis, the
value of this input is very asymetrical between the players, maybe a
simpler version could be used for at least one of them. That's assuming
one can come up with something approximate that is much faster but not
too less accurate.
