Question about the graph type of the alpha algorithm

On behalf of Tahereh Sadat Mousavi who asked the following question to Eric Verbeek:

Dear Eric.,



I have a beginner question about  Petri Net models that  are output
of Alpha algorithm, are they  directed multi graphs ? I think , output of
Alpha algorithm can be a cyclic graph ,is it true?

Do you know an algorithm that can find all paths form start node to end node in
these graphs?



Thank you very much in advance

With best regard

    Dear Tahereh,

    They are directed graphs, but I do not understand your “multi
    graphs”. Yes, the output of the Alpha algorithm can be a graph that contains
    cycles, therefore, the result is not necessarily acyclic. In general, there is
    no algorithm to find all paths in a cyclic graph, as (due to the cycles) the
    number of paths is infinite.

    Cheers,

     Eric.
