Best for Teams solving large-scale linear or mixed-integer optimization problems in production who need a fast, well-supported commercial solver. Enterprises already on IBM's stack that need a mature commercial solver plus constraint programming for scheduling problems. Organizations already using FICO's decisioning stack who need a commercial solver embedded in the same platform. Engineering teams building routing, scheduling or packing optimization into a product without a commercial solver license.
