Hello, by running tsp.cpp in the examples directory, I noticed that for the third hardcoded problem instance (br17 from TSPLIB), the solution returned is of cost 87, while the optimal solution reported by TSPLIB is 39. By copy and pasting the hardcoded data instance from tsp.cpp into a custom model that combines the cost-less version of circuit with another constraint to handle the costs independently, I was able to get the 39.
