In such cases, a Petri net rather than a serial state-transition graph, is a more
appropriate modeling and computational framework. Mauch (2006) describes a
software tool based upon this idea that can be used to solve a very large class
of DP problems; in essence, a Petri net model, called a Bellman net in Lew
(2002), is adopted as an internal data structure representation for a given DP
functional equation. This tool automatically constructs a Bellman net model
of a DP functional equation, from which it is possible to automatically generate
ordinary or parallel processing code to solve this equation.
