graph algorithmWe present a new polynomial-time heuristic algorithm for finding a solution to the Travelling Salesman Problem (TSP) for any complete and edge-weighted graph K n, with a set of vertices V and a set of edges E where | V| = n. In a few words, this method is based on ...
构建TSP,如果C上遍历一个vertex两次,则跳过这个vertex直接visit下一个vertex 2-Approximation algorithm C∗是optimal tour的开销,必然有 MST≤C∗ 这是因为C∗移除一条边必然构成G的生成树,因此 Cost(Eulerian tour)≤2C∗Cost(final output)≤2C∗ 1.5 approximation algorithm of TSP Algorithm 获得MST ...

Approximation algorithmPerformance guaranteeIn this paper, we study the path version of the Traveling Salesman Problem with the edge cost function satisfying a "relaxed" form of triangle inequality called the biased triangle inequality. We denote this problem as the Biased-TSP-Path . In this paper,...
