DecisionBrain provides packaged workers that allow to solve optimization problems, with IBM Ilog optimization solver, out of the box. Two different workers are packaged, for compatibility reasons. The first one supports Cplex and CpOptimizer, using IBM ILOG Java API. The second one supports OPL, using IBM ILOG Java API. IBM ILOG CPLEX Optimization Studio 12.9 has been used.
All logs from the solvers are redirected to the Optimization Server master, and available on the web console.
IBM ILOG Cplex is a solver that can handle (Mixed Integer) Linear Problems, and also convex quadratic problems. CpOptimizer, on the other hand, solves Constraint Satisfaction Problems.
Below are all tasks defined in this worker:
OPL is the IBM ILOG Optimization Programming Language that simplifies modeling and solving optimization problems. “OplTask” can solve problems in OPL format. The solution found is sent back as an output, in standard OPL solution text format. Possible task inputs are:
