set.branch.mode

Specify which branch to take first in the branch-and-bound algorithm for decision variables in an lpSolve linear program model object.

programming

The lpSolveAPI package provides an R interface to 'lp_solve',
a Mixed Integer Linear Programming (MILP) solver with support for pure
linear, (mixed) integer/binary, semi-continuous and special ordered sets
(SOS) models.
