set.branch.mode: Set Branch Mode

Description

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

Usage

set.branch.mode(lprec, columns, modes)

Arguments

lprec
an lpSolve linear program model object.
columns
a numeric vector containing values from the set {1, ..., n} (where n is the number of decision variables in lprec) specifying which columns to set the mode for.
modes
a character vector composed of the strings {"ceiling", "floor", "auto", "default"} giving the branch modes for the decision variables specified in columns. Please see the reference for a description of these terms.

Value

  • a vector of logical values indicating whether the branch modes were successfully set is invisibly returned.
