Description

Add a Special Ordered Set (SOS) constraint to an lpSolve linear program model object.

Usage

add.SOS(lprec, name, type, priority, columns, weights)

Arguments

lprec	an lpSolve linear program model object.
name	a character string specifying a name for the SOS constraint.
type	a positive integer specifying the type of the SOS constraint.
priority	an integer specifying the priority of the SOS constraint.
columns	a numeric vector of unique values from the set {1, ..., n} (where n is the number of decision variables in lprec) indicating which decision variables belong to the special ordered set.
weights	a numeric vector the same length as columns specifying the variable weights.
