- (graph theory) A tour that makes up part of a larger tour.
- 2015, Ulrich Pferschy, Rostislav Stanek, “Generating subtour elimination constraints for the TSP from pure integer solutions”, in arXiv[1]:
- The resulting problem is solved to integer optimality, violated constraints (which are trivial to find) are added and the process is repeated until a feasible solution is found. In order to speed up the algorithm we pursue several attempts to find as many relevant subtours as possible.
