QuadCoef

  • java.lang.Object
    • com.dashoptimization.objects.QuadCoef
  • public final class QuadCoef
extends java.lang.Object
    A quadratic coefficient. A quadratic coefficient is a (variable,variable)/value pair that gives the factor for a pair of variables in a quadratic expression.
    Since:
    43.00

      • QuadCoef

        public QuadCoef​(QPair variables,
                double coefficient)
        Create a new coefficient.
        Parameters:
        variables - The variables in the new coefficient.
        coefficient - Value multiplying the variables in the new coefficient.
        Since:
        43.00

      • QuadCoef

        public QuadCoef​(Variable var1,
                Variable var2,
                double coefficient)
        Create a new coefficient. Note that the constructor puts var1 and var2 into a canonical ordering and may thus change their order.
        Parameters:
        var1 - First variable in new coefficient.
        var2 - Second variable in new coefficient.
        coefficient - Value multiplying the variables in new coefficient.
        Since:
        43.00

      • QuadCoef

        public QuadCoef​(QuadCoef other)
        Since:
        43.00

      • QuadCoef

        public QuadCoef()
        Create a coefficient with default values.
        Since:

      • getVar2

        public Variable getVar2()
        Get the second variable in this quadratic coefficient.
        Returns:
        The second variable in this quadratic coefficient.
        Since:
        43.00
