Cardinal Optimizer (COPT) incorporates a full suite of solvers for linear and convex quadratic mixed-integer programming. It ranks at the top of benchmark tests on continuous linear programs, and has been fully extended to handle integer variables.
COPT downloads are available from the My Downloads page of your account at the AMPL Portal, and are included in the bundles that are used for free trials.
Developer: Cardinal Operations
Current version: 4.0.5
Problem types supported: Linear and convex quadratic optimization in continuous and integer variables.
Algorithms available: For continuous problems, primal and dual simplex, interior-point (barrier); for integer problems, branch-and-bound with presolve, feasibility heuristics, and cut generators.
