| 21. | The second stage, the'exploration phase'was manifested by looking at some branches of the game tree.
|
| 22. | Transposition tables are typically lossy and will omit or overwrite previous values of certain game tree nodes in its tables.
|
| 23. | In computing, the concept of ply is important because one ply corresponds to one level of the game tree.
|
| 24. | In game theory, a "'game tree "'is a directed graph whose edges are moves.
|
| 25. | The number of leaf nodes in the complete game tree is the number of possible different ways the game can be played.
|
| 26. | However, lost entries may require negamax to re-compute certain game tree node values more frequently, thus affecting performance.
|
| 27. | When evaluating a large game tree using techniques such as minimax or alpha-beta pruning, search depth is limited for feasibility reasons.
|
| 28. | For solving game trees with proof-number search family of algorithms, game trees are to be mapped to and-or trees.
|
| 29. | For solving game trees with proof-number search family of algorithms, game trees are to be mapped to and-or trees.
|
| 30. | Since such positions could not have resulted from best play, they and all branches of the game tree stemming from them can be ignored.
