Interface SolutionConstraint

public interface SolutionConstraint

* This interface allows accessing a constraint of the LP problem where each unknown variable has been assigned the optimal value. It is possible to obtain the LHS value of the constraint based on the optimal solution. By LHS component we mean the linear equation that occupies the left-hand side of the constraint. Given a constraint X1 + 3X2 ≥ 7, the LHS component is given by the part X1 + 3X2.
