GRBCallback.getNodeRel()

Retrieve node relaxation solution values at the current node. Only available when the where member variable is equal to GRB.CB_MIPNODE, and GRB.CB_MIPNODE_STATUS is equal to GRB.Status.OPTIMAL.

double getNodeRel ( GRBVar v )

    Arguments:

    v: The variable whose value is desired.

    Return value:

    The value of the specified variable in the node relaxation for the current node.

double[] getNodeRel ( GRBVar[] xvars )

    Arguments:

    xvars: The list of variables whose values are desired.

    Return value:

    The values of the specified variables in the node relaxation for the current node.

double[][] getNodeRel ( GRBVar[][] xvars )

    Arguments:

    xvars: The array of variables whose values are desired.

    Return value:

    The values of the specified variables in the node relaxation for the current node.
