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\leq 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)\leq 2C^*\\ Cost(final\ output)\leq 2C^* 1.5 approximation algorithm of TSP Al...
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 ...
Finally, we will provide a brief overview of linear programming algorithms including the famous Simplex algorithm for solving linear programs. The problem set will guide you towards posing and solving some interesting problems such as a financial portfolio problem and the optimal transportation problem ...
