PVS (Principal Variation Search) is a search algorithm to find the best move in a given position. It is an enhancement of the alpha-beta algorithm and uses null or zero window searches to confirm that a move is worse or not worse than an already safe score from the principal variation. PVS focuses on the most promising moves and avoids unnecessary searches of suboptimal branches, which helps improve the efficiency of the search.
PVS (Principal Variation Search) is 'n soekalgoritme om die beste skuif in 'n gegewe posisie te vind. Dit is 'n verbetering van die alfa-beta-algoritme en gebruik nul- of nul-venstersoektogte om te bevestig dat 'n skuif slegter of nie slegter is as 'n reeds veilige telling van die hoofvariasie nie. PVS fokus op die mees belowende bewegings en vermy onnodige soektogte van suboptimale takke, wat help om die doeltreffendheid van die soektog te verbeter.
