Abstract: The author shows that the problem of determining if there exists a reachable marking covering a given one in a 1-bounded conflict-free Petri net is solvable in polynomial time. The result generalises previous ones by Howell, Rossier and Yen.
Keywords: polynomial time algorithm (to solve) covering problem (for) 1-bounded conflict-free net; reachable marking.
