IloCplex::NodeCallbackI
protected IloNum getInfeasibilitySum(NodeId nodeid)
This method returns the sum of infeasibility measures at the node with the identifier
nodeid.
protected IloNum getInfeasibilitySum(int node)
This method returns the sum of infeasibility measures at the node indicated by the index
number node.
protected IloInt getNinfeasibilities(NodeId nodeid)
This method returns the number of infeasibilities at the node with the identifier
nodeid.
protected IloInt getNinfeasibilities(int node)
This method returns the number of infeasibilities at the node indicated by the index
number node.
protected NodeData * getNodeData(NodeId nodeid)
This method retrieves the NodeData object that may have previously been assigned by
the user to the node with the identfier nodeid with one of the methods
IloCplex::BranchCallbackI::makeBranch. If no data object has been
assigned to the that node, 0 (zero) will be returned.
protected NodeData * getNodeData(int node)
This method retrieves the NodeData object that may have previously been assigned to
the node with index node by the user with the method
IloCplex::BranchCallbackI::makeBranch. If no data object has been
assigned to the specified node, 0 (zero) will be returned.
protected NodeId getNodeId(int node)
This method returns the node identifier of the node indicated by the index number
node. During branch & cut, an instance of IloCplex assigns node identifiers
sequentially from 0 (zero) to (getNodes - 1) as it creates nodes. Within a search,
these node identifiers are unique throughout the duration of that search. However, at any
point, the remaining nodes, (that is, the nodes that have not yet been processed) are
stored in an array in an arbitrary order. This method returns the identifier of the node
stored at position node in that array.
protected IloInt getNodeNumber(NodeId nodeid)
Returns the current index number of the node indicated by the node identifier nodeid.
protected IloNum getObjValue(NodeId nodeid)
This method returns the objective value of the node with the identifier node.
protected IloNum getObjValue(int node)
