branchobj.validate

Purpose
Verifies that a given branching object is valid for branching on the current branch-and-bound node of a MIP solve. The function will check that all branches are non-empty, and if required, verify that the branching object can be presolved.
Synopsis
status = branchobj.validate ()
Argument
status 

The returned status from checking the provided branching object:

0 

The object is acceptable.
1 

Failed to presolve the object due to dual reductions in presolve.
2 

Failed to presolve the object due to duplicate column reductions in presolve.
3
