More solution methods for the TSP

More solution methods for the TSP. 1. If we use the assignment problem relaxation, how can we find subtours? Answer: Use a subtour constraint generator. 2. Is there an LP for the minimum spanning tree? Answer: Yes! 3. Then do we have another TSP formulation? Answer: Yes!.

Exact methods for ALB

Exact methods for ALB. ALB problem can be considered as a shortest path problem The complete graph need not be developed since one can stop as soon as in one node all operations have been assigned, and also because of pruning the tree by dominance rules
