xpress.branchobj

Purpose

Class for branching objects. These objects are created by the user within a callback when directing a branch-and-bound solve toward different branching decisions.


Synopsis
b = xpress.branchobj(prob, branches=None, isoriginal=True)
Arguments
prob 
Problem object.
branches 
List or tuple of branching decisions. If it is a tuple, its members are constraints of distinct branches; if it is a list, its members must be either tuples of branching constraints, each tuple for a single branch (deprecated).
isoriginal 
False 
Column indices should refer to the current (presolved) node problem;
True 
Column indices should refer to the original matrix.
Further information
The branches argument is deprecated. Branches should be added after creating the branchobj using branchobj.addbranches and branchobj.addrows.
