Public Member Functions | |
| native PIP_Solution_Node | as_solution () |
Returns the solution node if this is a solution node, and 0 otherwise. | |
| native PIP_Decision_Node | as_decision () |
Returns the decision node if this is a decision node, and 0 otherwise. | |
| native boolean | OK () |
| Returns true if the pip tree is well formed, i.e., if it satisfies all its implementation invariants; returns 0 and perhaps makes some noise if broken. Useful for debugging purposes. | |
| native long | number_of_artificials () |
| Returns the number of artificial parameters in the PIP_Tree_Node. | |
| native Artificial_Parameter_Sequence | artificials () |
| Returns the sequence of (Java) artificial parameters in the PIP_Tree_Node. | |
| native Constraint_System | constraints () |
| Returns the system of parameter constraints controlling the PIP_Tree_Node. More... | |
| native String | toString () |
Returns a string representation of this. | |
Detailed Description
A node of the PIP solution tree.
This is the base class for the nodes of the binary trees representing the solutions of PIP problems. From this one, two classes are derived:
- PIP_Decision_Node, for the internal nodes of the tree;
- PIP_Solution_Node, for the leaves of the tree.
Member Function Documentation
| native Constraint_System parma_polyhedra_library.PIP_Tree_Node.constraints | ( | ) |
Returns the system of parameter constraints controlling the PIP_Tree_Node.
The indices in the constraints are the same as the original variables and parameters. Coefficients in indices corresponding to variables always are zero.
The documentation for this class was generated from the following file:
- PIP_Tree_Node.java
