problem.addIndicator
problem.addIndicator |
Purpose
Adds one or more indicator constraints to the problem.
Synopsis
problem.addIndicator(c1, c2, ...)
Argument
|
c1,c2...
|
Tuples containing an indicator constraints, or list/tuples/array of tuples containing a binary condition and a constraint.
|
Example
x = xpress.var(vartype=xpress.binary) y = xpress.var(lb=10, ub=20) z = xpress.var() ind1 = (x==1, y+z <= 40) p = xpress.problem() p.addVariable(x,y,z) p.addIndicator(ind1)
Further information
All arguments can be single indicator constraints or lists, tuples, or NumPy arrays created as indicator constraints. An indicator constraint is a tuple of two elements, the first being a condition (i.e. a binary variable being 0 or 1) and the second being the constraint.
