WebDec 6, 2015 · Modified 7 years, 3 months ago. Viewed 6k times. 3. I have written code to implement the nearest neighbour algorithm to produce a solution for the TSP problem. On my machine, the code takes roughly 10 seconds. Since this is so short, a lot of the profilers I have tried don't get a chance to record it properly. WebCheapest insertion - Start from a random city. - Find the city which insertion in the tour causes the smallest increase in length, i.e the city k which minimizes d(i, k) + d(k, j) - d(i, j) with (i, j) an edge in the partial tour. - Insert k between i and j. - Repeat until every city has been visited. Farthest insertion - Start from a random city.
