ILOG CPLEX 11.0 User's Manual > Discrete Optimization > Solution Pool: Generating and Keeping Multiple Solutions > Impact of Change on the Solution Pool > Changes between MIP Optimization and Populate

What might users do between a call of MIP optimization and a call of populate or between successive calls of populate?

Users can continue to call populate until they have a pool of solutions they are satisfied with. Between calls, users may examine solutions. If the solutions are satisfactory, users can stop calling populate. If the solutions are not satisfactory, then users can make changes to improve the solution pool. Changes that have an impact on the solutions that populate generates and stores include these:

Changes of the model itself, such as altering the objective function, are treated differently. For details, see Model Changes and the Solution Pool.
