# 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 | The object contains an empty branch.
