Purpose
Set a directive on a variable or Special Ordered Set.
Synopsis
procedure setmipdir(x:mpvar,t:integer,r:real)
procedure setmipdir(x:mpvar,t:integer)
procedure setmipdir(c:linctr,t:integer,r:real)
procedure setmipdir(c:linctr,t:integer)
Arguments
x 
A decision variable
c 
A linear constraint (of type SOS)
r 
A real value
t 
Directive type, which may be one of:
XPRS_PR 
r is a priority (integer value between 1 and 1000 where 1 is the highest priority, 1000 the lowest)
XPRS_UP 
Force up first
XPRS_DN 
Force down first
XPRS_PU 
r is an up pseudo cost
XPRS_PD 
r is a down pseudo cost
XPRS_BR 
Force branching even if satisfied
