计算机象棋中的信息与搜索

Information and Search in Computer Chess

摘要:

本文描述了一个基于信息论的国际象棋模型。概述了部分深度方案的数学模型,并根据模型的原理计算出每层所增加的部分深度的公式。给出了部分深度的alpha-beta算法的一个实现。该方法使用实验策略进行测试,其目标是显示在具有较高信息的搜索树的区域上分配较高量的搜索资源的效果。搜索在具有较高信息增益的线的方向上进行。实验测试了在高信息增益的线路上分配高搜索资源对搜索性能的影响,得到了结论性的结果。为了隔离部分深度方案的影响,不使用其他启发式算法。

英文摘要:

The article describes a model of chess based on information theory. A mathematical model of the partial depth scheme is outlined and a formula for the partial depth added for each ply is calculated from the principles of the model. An implementation of alpha-beta with partial depth is given. The method is tested using an experimental strategy having as objective to show the effect of allocation of a higher amount of search resources on areas of the search tree with higher information. The search proceeds in the direction of lines with higher information gain. The effects on search performance of allocating higher search resources on lines with higher information gain are tested experimentaly and conclusive results are obtained. In order to isolate the effects of the partial depth scheme no other heuristic is used.
