Primary Optimization Functions

Using just these three functions, you will be able to define any optimization and view results.

• DefineOptimization()
• OptSolution()
• OptObjective()
• OptObjectivesa()

Optimization Status Functions

Optimization status functions can reveal important details such as the selected engine matrix coefficients, and other information that may be helpful with troubleshooting. These functions are:

• OptStatusNum(Opt) / OptStatusText(Opt)
• OptInfo(Opt, "Item", Decision, Constraint, asRef)
• OptEngineInfo("Engine", "Item", asRef)
• OptShadow(Opt, Constraint, PassNonFeasible)
• OptReducedCost(Opt, Decision, PassNonFeasible)
• OptObjectiveSa(Opt, Decision)
• OptRhsSa(Opt, Constraint)
• OptSlack(Opt, Constraint, PassNonFeasible)
• OptFindIIS(Opt, newLp)
• OptWriteIIS(Opt, filename, format)
• OptRead(Opt, DecisionVector, ConstraintVector, format)
• OptWrite(Opt, filename, format)
