Constraint

public Constraint(double[] Aj,
                  ConsType rel,
                  double rhs)
           throws LPException

Parameters:

Aj - The LHS part of the j-th constraint of the problem

rel - The type of constraint/relation (EQ, LE, GE, UPPER, LOWER, INT, BIN, SEMICONT)

rhs - The RHS part of the constraint or coefficient bj

Throws:

LPException - If the constraint is not congruent
