Abstract: We introduce the general postman problem firstly, involving issues such as serving and traversing cost, sides of serving, turn cost and serving hierarchy and so on. We then survey briefly the research on the Chinese postman problem, the Chinese postman problem on directed graphs, postman problems on mixed graphs, on graphs with wind and on rural districts, focusing on their linear programming formulations and the structures of the corresponding polyhedra, addressing the models of problems, exact algorithms and their time complexities, and the approximation approaches and their performance.

Key words: Chinese postman problem, heuristic, computational complexity, performance ratio
