| Abstract(in English) | The graph inference from a walk for a class C of undirected edge- colored graphs is,given a string x of colors,finding the smallest graph in C that realizes a walk whose sequence of edgecolors coincides with x.It has been known that the problem for graphs of bounded degree k(【greater than or equal】3)is NP-complete,while th e problem for trees without degree bound lias been known to be solvable in O(n)time,where n is the length of the string.Then we prove that the graph inference from a walk for trees of bounded degree k(【greater than or equal】3)is NP-complete.Furthermore,the problem for a special case of trees of bounded degree 3,called(1, 1)-caterpillars,is shown NP-complete. |
