Chinese Postman Problem on bidirected graphs
| 1: ifG is not connected then return “no circuit exists” |
| 2: Use algorithm of (Gabow, 1983) to solve the corresponding minimum cost bidirected flow (see text). |
| 3: if there is no solution then return “no circuit exists” |
| 4: Let G′ be the graph G with f(e) copies of every edge e, in addition to e itself. |
| 5: Use a standard algorithm to find an Eulerian circuit W of G′. |
| 6: Relabel W according to Theorem 3. |
| 7: returnW |
