| namespace | GoEyeUtil |
Functions | |
| int | GoEyeUtil::DegreeCode (const SgPointSet &points) |
| Code for how many points of each degree there are. | |
| long | GoEyeUtil::DegreeCode8 (const SgPointSet &points) |
| Like DegreeCode, but also count diagonal neighbors. | |
| template<class BOARD> | |
| SgPoint | GoEyeUtil::EmptyNeighbor (const BOARD &bd, SgPoint p) |
| Return an empty neighbor of p. | |
| bool | GoEyeUtil::IsNakadeShape (const SgPointSet &area) |
| Check if area is one of the classical nakade shapes: ,**,***, **, ***, **, ***, * , * . | |
| bool | GoEyeUtil::IsSimpleEye (const GoBoard &bd, SgPoint p, SgBlackWhite c) |
| Check if point is a single point eye with one or two adjacent blocks. | |
| bool | GoEyeUtil::IsSinglePointEye (const GoBoard &bd, SgPoint p, SgBlackWhite c) |
| bool | GoEyeUtil::IsPossibleEye (const GoBoard &board, SgBlackWhite color, SgPoint p) |
| Return true if a point can become an eye by adding one more defender's move. | |
| bool | GoEyeUtil::CanBecomeSinglePointEye (const GoBoard &board, SgPoint p, const SgPointSet &oppSafe) |
| Given opponent's safe stones, can p ever become an eye? Checks direct and diagonal neighbors. | |
| template<class BOARD> | |
| bool | GoEyeUtil::MakesNakadeShape (const BOARD &bd, SgPoint p, SgBlackWhite toPlay) |
| does playing at p create one of the standard nakade shapes? | |
| bool | GoEyeUtil::NumberOfMoveToEye (const GoBoard &bd, SgBlackWhite c, SgPoint p, int &number) |
| Return true if a point can become an eye by adding number of defender's move. | |
| bool | GoEyeUtil::IsSinglePointEye2 (const GoBoard &bd, SgPoint p, SgBlackWhite c) |
| As IsSinglePointEye, but allows diagonal points to be eyes. | |
| bool | GoEyeUtil::IsSinglePointEye2 (const GoBoard &bd, SgPoint p, SgBlackWhite c, SgVector< SgPoint > &eyes) |
| As IsSinglePointEye2, but specifying points assumed to be eyes. | |
| template<class BOARD> | |
| bool | GoEyeUtil::IsTwoPointEye (const BOARD &bd, SgPoint p, SgBlackWhite c) |
| p is in a 2 point eye surrounded by a single chain | |
| bool | GoEyeUtil::NumberOfMoveToEye2 (const GoBoard &bd, SgBlackWhite c, SgPoint p, int &nummoves) |
| As NumberOfMoveToEye2, but includes existing diagonal eyes, and allows opponent stones to be captured. | |
| int | GoEyeUtil::CountSinglePointEyes2 (const GoBoard &bd, SgPoint p) |
| Count number of single point eyes for block p. | |
| bool | GoEyeUtil::SinglePointSafe2 (const GoBoard &bd, SgPoint p) |
| Does block at p have two or more single point eyes? | |
| bool | GoEyeUtil::IsSplitPt (SgPoint p, const SgPointSet &s) |
| Does removing p split s into two or more parts? | |
| bool | GoEyeUtil::IsLocalSplitPt (SgPoint p, const SgPointSet &set) |
| Does p locally,within a 3x3 region, split its neighbors in s? Even if the reply is 'yes', s might still be connected outside the region. | |
| bool | GoEyeUtil::IsTreeShape (const SgPointSet &area) |
| Area is tree shape if it does not contain a 2x2 square. | |
| bool | GoEyeUtil::IsVitalPt (const SgPointSet &points, SgPoint p, SgBlackWhite opp, const GoBoard &bd) |
| Vital point in small shape - usually has most liberties See implementation for details. | |
| void | GoEyeUtil::TestNakade (const SgPointSet &points, const GoBoard &bd, SgBlackWhite color, bool isFullyEnclosed, bool &isNakade, bool &makeNakade, bool &makeFalse, bool &maybeSeki, bool &sureSeki, SgPoint *vital) |
| Analyze small region locally for number of eyes. | |
| bool | GoEyeUtil::CheckInterior (const GoBoard &bd, const SgPointSet &area, SgBlackWhite opp, bool checkBlocks) |
| bool | AreSameBlocks (const SgPoint anchors1[], const SgPoint anchors2[]) |
| template<class BOARD> | |
| SgPoint | GoEyeUtil::EmptyNeighbor (const BOARD &bd, SgPoint p) |
| Return an empty neighbor of p. | |

| p is in a 2 point eye surrounded by a single chain | |
| template<class BOARD> | |
| bool | GoEyeUtil::MakesNakadeShape (const BOARD &bd, SgPoint p, SgBlackWhite toPlay) |
| does playing at p create one of the standard nakade shapes? | |
