Shortest Common Superstring
By albeXL, history, 7 years ago, In English

Can someone help me solve this problem? Given N <= 16 strings I need to find the shortest(in length) string that contains all N strings as a substring, in case of a tie I need to find the smallest one in lexicographic order. Thanks in advance

And what about length of the strings?

Depending on lengths of the strings this can be the same or an easier version of : http://codeforces.me/problemset/gymProblem/101064/E

Construct an Aho-Corasick automaton and do a BFS for find the shortest path that goes through every final state.
