GRBCallback::getNodeRel()

Retrieve values from the node relaxation solution 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_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 ( const GRBVar* xvars,
    int len )
    Arguments:

    xvars: The list of variables whose values are desired.

    len: The number of variables in the list.

    Return value:

    The values of the specified variables in the node relaxation for the current node. Note that the result is heap-allocated, and must be returned to the heap by the user.
