This page provides tables with the current
best-known feasible solution for each CPIT and PCPSP instance of each
mine. Additionally, we provide the objective value of the optimal LP
relaxation of each instance, which is a valid upper bound.

Click on mine name for further details about the solution.

- UPIT value: optimal objective value of the problem
- CPIT LP upper bound: objective value of the optimal LP relaxation of each CPIT instance.
- CPIT best known feas. sol.: objective value of the best-known feasible solution of each CPIT instance.
- CPIT Gap (%): Gap of the best feasible solution, compared with the
LP upper bound.
