我们描述了一个计算离散概率规划边际分布的动态规划算法。该算法对任意概率编程语言采用函数解释器，并将其转化为有效的边际化器。因为在递归的情况下不可能直接缓存子分布，所以我们建立了子分布之间的依赖关系图。这种因数和积网络使子问题之间的依赖关系（潜在的循环）显式化，并对应于边际分布的方程组。我们用拓扑顺序的不动点迭代来求解这些方程。我们通过在概率模型教学、计算认知科学研究和博弈论中使用的例子来说明该算法。

英文摘要：
We describe a dynamic programming algorithm for computing the marginal distribution of discrete probabilistic programs. This algorithm takes a functional interpreter for an arbitrary probabilistic programming language and turns it into an efficient marginalizer. Because direct caching of sub-distributions is impossible in the presence of recursion, we build a graph of dependencies between sub-distributions. This factored sum-product network makes (potentially cyclic) dependencies between subproblems explicit, and corresponds to a system of equations for the marginal distribution. We solve these equations by fixed-point iteration in topological order. We illustrate this algorithm on examples used in teaching probabilistic models, computational cognitive science research, and game theory.
