WebNodes in the coverability graph correspond to the unique markings in the coverability tree. In the coverability graph, there is an edge from m to m 0, labeled with transition t, if • t is enabled in marking m, and • the firing of t in m leads to marking m 00 with m 0 ≥ m 00. Example 7.2 The coverability graph for the previous example is ... WebThe above tree representation, however, will grow infinitely large if the net is unbounded. To keep the tree finite, we introduce a special symbol ω, which can be thought of as ”infinity.” It has the properties that for each integer n, ω>n, ω±=n ω and ω≥ω. The coverability tree for a Petri net (, )NM0 is constructed by the following
