#include <SgSearchValue.h>
There's a range of values that indicate that the problem has been solved (at a certain depth), a range of values for solutions that involve ko, and a range of values for problems that have not been solved yet. Value is always stored with positive values being good for black, negative values being good for white.
int v = Board().ToPlay() == SG_WHITE ? -value : +value;

| MAX_LEVEL = 125 | |
| MAX_VALUE = MAX_LEVEL * SgSearch::MAX_DEPTH | |
| The best possible search result - highest possible value. | |
| MIN_VALUE = -MAX_VALUE | |
| The worst possible search result. | |
| MAX_KO_LEVEL = 3 | |
| The maximum number of Ko recaptures allowed in a search. | |
| KO_VALUE = MAX_VALUE - SgSearch::MAX_DEPTH | |
| KO_VALUE is the result for win by ko. | |
| MIN_PROVEN_VALUE | |
| MIN_PROVEN_VALUE is the lowest score that indicates a proven win. | |
