除理论之外，这种专注表现在本身复杂性的理论，它根据它们运行的时间和空间需求来组织算法。

At the theoretical end, this focus manifests itself in complexity theory, which groups algorithms according to their time and space requirements for execution.

而在使用相同方法的其他算法中，采用有效的棋盘表现方法是一个介于复杂性，速度和空间需求之间的权衡。

In the same way as other algorithms, the use of efficient board representations is a tradeoff between complexity, speed, and space requirements.
