A detailed description of several separation
algorithms for combs and clique trees. These algorithms were used by the
authors to solve a series of TSPLIB test instances, including pcb3038,
fnl4461, and pla7392. Certificates of the optimality of these three large
instances were made available on the internet by the authors.
