Planning problems are a set of problems in which an objective must be reached by a sequence of actions. Planning problems traditionally do not consider uncertainty, however for most real-world planning problems uncertainty must be considered to create effective plans. The objective of this paper is to use an existing deterministic planning algorithm in order to create robust plans that solve an uncertain version of Sokoban called Uncertain Move Sokoban. To this end a probabilistic programming language, Gen.jl, is used, which enables creating probabilistic models and inferring its parameters using code. A probabilistic model is created in Gen.jl, that generates plans for the problem as well as robustness scores using a simulator embedded in the model. Probabilistic inference techniques are then used to obtain a robust plan for the uncertain problem, namely: importance sampling and Metropolis-Hastings. We find that the technique is able to create robust plans for small to medium-sized problems and that Metropolis-Hastings is the better-performing inference technique.
