基于案例的规划复杂性研究

On the Complexity of Case-Based Planning

Paolo Liberatore

摘要:

我们分析了计算复杂性的问题,基于案例的规划:规划时,一个类似的实例的计划是已知的,规划从一个图书馆的计划。我们证明,从一个单一的情况下规划具有相同的复杂性比生成规划(即,规划“从无到有”);使用扩展的案例定义,如果存储在案例中的域与要搜索计划的域相似,则降低复杂性。从图书馆的情况下,规划显示具有相同的复杂性。在这两种情况下,规划的复杂性仍然是,在最坏的情况下,PSPACE完成。

英文摘要:

We analyze the computational complexity of problems related to case-based planning: planning when a plan for a similar instance is known, and planning from a library of plans. We prove that planning from a single case has the same complexity than generative planning (i.e., planning "from scratch"); using an extended definition of cases, complexity is reduced if the domain stored in the case is similar to the one to search plans for. Planning from a library of cases is shown to have the same complexity. In both cases, the complexity of planning remains, in the worst case, PSPACE-complete.
