Is it possible to determine all the multiple global optima for a MILP using CPLEX during the solution of the optimization problem?
Please note that we are interested to find all these multiple optimal solutions in a single run of the problem.

Hi,

have you had a look at solution pools?

The solution pool allows you to generate and store multiple solutions to a mixed integer programming (MIP) model. This feature uses an extension of the IBM ILOG CPLEX branch-and-cut algorithm to generate multiple solutions in addition to the optimal solution.
In the documentation IDE and OPL > CPLEX Studio IDE > IDE Tutorials you will see

Working with the solution pool

Explains how to access a project solution pool in the IDE and how you can set options and define filters on solution pool generation.
