problem.getindicators

Purpose

Returns the indicator constraint condition (indicator variable and complement flag) associated to the rows in a given range.

Synopsis

problem.getindicators (inds, comps, first, last)

Arguments

inds

Array of length last-first+1 where the column indices of the indicator variables are to be placed.

comps

Array of length last-first+1 where the indicator complement flags will be returned:

0	not an indicator constraint (in this case the corresponding entry in the inds array is ignored);
1	for indicator constraints with condition " bin = 1";
-1	for indicator constraints with condition " bin = 0";

first

First row in the range.

last

Last row in the range (inclusive).

Example

The following example retrieves information about three indicator constraints in the problem and prints a list of their indices.

inds = []
comps = []
p.getindicators (inds, comps, 2, 4)
print ("indices:",          inds)
print ("complement flags:", comps)
