Property Detail

solutionValue

{float} solutionValue

Value in the current solution for the objective.

Available for:: postprocessing; flow control

Method Detail

setCoef

setCoef(dvar, coef)

Changes the coefficient of a decision variable in the invoking objective. This method is limited to objectives that use simple real linear expressions with no aggregation. In other cases, use the method from the IloCplex class.

Parameters:: dvar - Decision variable.; coef - The new linear coefficient.

Available for:: all
