The feedback vertex set problem (FVSP). a combinatorial optimization problem. finds a set of vertices that intersect all cycles of the directed graph. One of the cutting-edge heuristics for this problem is a simulated annealing (SA)-based algorithm named the SA-FVSP. https://www.ealisboa.com/top-save-RE-DESIGNED-Strikketoy-oppbevaring-Prosjekt-27-Sort-100-Skinn-great-save/
