Detailed Description

Base class for hashing for general type patterns (currently works only for corner patterns).

Member Function Documentation

void Algo_hash::get_HHCS ( int  ptr, vector< HashhitCS * > *  results, bool  cs  )

protectedvirtual

takes a pointer to os_data, a vector results, and a bool cs (==colorSwitch) and adds the hits from the database to the results vector:

int Algo_hash::search ( PatternList &  patternList, GameList &  gl, SearchOptions &  options  )

virtual

Do a pattern search for the Pattern specified by patternList, in the GameList gl.

This computes the hashCode for the given pattern, looks it up in the database, and turns all records found there into Candidate entries which can be used by Algo_movelist::search If more than one corner lies inside the pattern, the hashCode for the corner which contains most stones is used.

Reimplemented from Algorithm.
