Chinese postman problem in graph theory pdf
WebIn graph theory, an Euler cycle in a connected, weighted graph is called the Chinese Postman problem. Graph theory. Graph theory is very useful in solving the Chinese … WebOct 19, 2024 · An algorithm for finding an optimal Chinese postman route is: List all odd vertices. List all possible pairings of odd vertices. For each pairing find the edges that connect the vertices with the minimum weight. Find the pairings such that the sum of the weights is minimised. On the original graph add the edges that have been found in Step 4.
