摘要:

本文在信任网络算法的基础上,提出了一种新的求解影响图决策问题的算法。决策节点关联到不精确的概率分布和重新制定的介绍,发现全球最大的战略相对于预期的效用。我们使用有限内存影响图,它概括了大多数影响图建议并处理同时决策。除了全局最优方法,我们探索了一个随时近似的解决方案,保证最大误差,并表明不精确的概率处理在一个简单的方式。讨论了随机图的复杂性问题和实验以及基于效果的军事规划问题。

英文摘要:

This paper describes a new algorithm to solve the decision making problem in Influence Diagrams based on algorithms for credal networks. Decision nodes are associated to imprecise probability distributions and a reformulation is introduced that finds the global maximum strategy with respect to the expected utility. We work with Limited Memory Influence Diagrams, which generalize most Influence Diagram proposals and handle simultaneous decisions. Besides the global optimum method, we explore an anytime approximate solution with a guaranteed maximum error and show that imprecise probabilities are handled in a straightforward way. Complexity issues and experiments with random diagrams and an effects-based military planning problem are discussed.
