In this paper, we show that some graph-related NP-complete problems can be represented by Petri nets moldel and that the question for an NP-complete problem can be changed to a reachability problem for the corresponding Petri net. All problems in the paper are modeled with low level Petri nets.
Every modeling has been dine with polynomially bounded nimber of lpaces, transitions, arcs and initial tokens with respect to |V|,|E| and K if the original problem is specified with a graph G=(V,E) and a constant K.
