|Returns the decision node if |
|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. |

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:
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.
