WebBranch-and-Cut for TSP Branch-and-Cut is a general technique applicable e.g. to solve symmetric TSP problem. TSP is NP-hard – no one believes that there exists a polynomial algorithm for the problem. TSP can be formulated as an integer programming problem – for an n-vertex graph the number of binary variables becomes n(n 1) 2, dave and busters lawn mower salad
