When the problem calls for a minimal traversal of a digraph (or multidigraph) it is known as the "New York Street Sweeper problem." [13] The k-Chinese postman problem: find k cycles all starting at a designated location such that each edge is traversed by at least one cycle. The goal is to minimize the cost of the most expensive cycle.
He published his work on the route inspection problem in 1960, and his paper was translated into English in 1962. [1] It attracted the attention of Jack Edmonds, who gave the problem its alternative name, the "Chinese postman problem", in honor of Guan, [3] and proved that this problem can be solved optimally in polynomial time.

The mixed Chinese postman problem (MCPP or MCP) is the search for the shortest traversal of a graph with a set of vertices V, a set of undirected edges E with positive rational weights, and a set of directed arcs A with positive rational weights that covers each edge or arc at least once at minimal cost.
