WebOct 25, 2011 · Alpha Beta Pruning uses two dynamically computed bounds alpha and beta to bound the values that nodes can take. Alpha is the minimum value that the max player is guaranteed (regardless of what the min player does) through another path through the game tree. This value is used to perform cutoffs (pruning) at the minimizing levels. WebDec 22, 2024 · The process of obtaining the goal is slower due to the large branching factor. The engine's performance and efficiency suffer as a result of evaluating and searching all conceivable nodes and branches. Both players have an excessive number of options from which to choose.
