Two Algorithms Suitable for Constructive Utility Planning

We discuss two algorithms suitable for constructive utility planning using both actions and observations, which are based on iterative plan modification instead of n-step plan generation. We have analysed runtime costs and solution quality both theoretically and on a set of examples. For most situations we analysed, our algorithms perform better than conventional plan generation algorithms using n-step look-ahead, yielding a family of algorithms which can be applied advantageously for constructive utility planning taking both actions and observations into account.
