当不满足完全回忆时，混合策略和行为策略的信息量不同，且比信息划分所描述的信息量要多。首先，我们考虑了两种额外的信息策略可能携带，并证明了这样的信息导致完美的回忆细化一个给定的信息划分。然而，这并不意味着这些策略完全弥补了完美回忆的不足。我们给出了一个充分必要条件的信息分区，称为A-损失，混合策略的信息内容，以充分弥补缺乏完美的回忆。行为策略的信息内容永远无法完全补偿。
When perfect recall is not satisfied, the informational contents of mixed and behavior strategies differ and are more than what the information partition describes. First, we consider two kinds of additional information strategies may carry, and show that such information leads to theperfect recall refinement of a given information partition. This does not, however, imply that the strategies compensate fully for the lack of perfect recall. We give a necessary and sufficient condition on an information partition, calledA-loss, for the informational content of mixed strategies to fully compensate for the lack of perfect recall. The informational content of behavior strategies never fully compensates.
