Purpose
Creates
a special ordered set (SOS) using a set of decision variables and a linear constraint.
Synopsis
procedure makesos1(cs:linctr, s:set of mpvar, c:linctr)
procedure makesos1(s:set of mpvar, c:linctr)
procedure makesos2(cs:linctr, s:set of mpvar, c:linctr)
procedure makesos2(s:set of mpvar, c:linctr)
Arguments
|
cs
|
A linear constraint
|
|
s
|
A set of decision variables
|
|
c
|
A linear constraint
|
Example
The following generates the SOS1 set mysos based on the linear constraint rr. The resulting set contains the variables x, y, and z with the weights 0,2, and 4.
declarations
x,y,z: mpvar
rr,mysos: linctr
end-declarations
rr:= 2*y+4*z
makesos1(mysos, {x,y,z}, rr)
Further information
These procedures generate a SOS set containing the decision
variables of the set s with the coefficients of the
linear constraint c.
The resulting set it assigned to cs if it is provided. Note that these procedures simplify the generation of SOS with weights of value 0.
