Abstract. Many graph problems require us to nd subgraphs satisfying constraints such as no cycle, connected, degree-bounded and so on. Frontier-based search is a framework to construct a compressed data structure ZDD storing all subgraphs satisfying constraints in a given graph. Since frontier-based search processes edges one by one in a given order, we should determine an edge order of a given graph as input for frontier-based search. The performance of frontier-based search, including the size of a constructed ZDD, deeply depends on what edge order is given. In this paper we propose a meta-heuristic algorithm to determine a good edge order for frontier-based search. Since this ordering problem is related to minimum path-width problem, our method can also be considered as a method for minimum path-width problem. Experimental results show our method is useful for both of frontier-based search and minimum path-width problem.
