set.branch.mode {lpSolveAPI} | R Documentation |
Specify which branch to take first in the branch-and-bound algorithm for decision variables in an lpSolve linear program model object.
set.branch.mode(lprec, columns, modes)
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. |
a vector of logical values indicating whether the branch modes were successfully set is invisibly returned.
