摘要:

完全可观测的非确定性(FOND)规划正变得越来越重要,作为一种方法来计算适当的政策,在概率规划,LTL规划的扩展时间计划,广义规划的一般计划。在这项工作中,我们引入了一个SAT编码FOND规划,是紧凑的,可以产生紧凑的强循环的政策。编码的简单变化也被引入用于强规划和我们所谓的双重FOND规划,其中一些不确定的动作被假设为公平的(例如,概率性的)和其它不公平的(例如,对抗性的)。由此产生的FOND规划者与现有的规划者在现有的和新的基准经验进行比较。“概率有趣的问题”的概念也重新审视,以产生一个更全面的图片的优势和局限性,目前FOND规划和拟议的SAT方法。

英文摘要:

Fully observable non-deterministic (FOND) planning is becoming increasingly important as an approach for computing proper policies in probabilistic planning, extended temporal plans in LTL planning, and general plans in generalized planning. In this work, we introduce a SAT encoding for FOND planning that is compact and can produce compact strong cyclic policies. Simple variations of the encodings are also introduced for strong planning and for what we call, dual FOND planning, where some non-deterministic actions are assumed to be fair (e.g., probabilistic) and others unfair (e.g., adversarial). The resulting FOND planners are compared empirically with existing planners over existing and new benchmarks. The notion of "probabilistic interesting problems" is also revisited to yield a more comprehensive picture of the strengths and limitations of current FOND planners and the proposed SAT approach.
