I am working on 2 multi-objective problem with two objective functions (one is to maximize the lecturers’ preference and the other is to maximize students’ preference). I have many constraints and only one decision variable (for the first problem) while many decision variables for the second problem.

Version 12.8 of IBM CPLEX Optimization Studio is available to customers, teachers and students since December 2017. Among other features, it offers a new callb.
SHOT supports the open-source solver Cbc (2.10 or newer), and the commercial solvers CPLEX (12.8 or newer) and Gurobi (8.0 or newer). If you are an academic user, you can download free versions of both CPLEX and Gurobi.
The tutorial that AIMMS provided is for CPLEX 12.9. Can it still be used for CPLEX 12.8? Portable smart board on wheels tires. Lambretta serial numbers list. Cyberghost trial download. If not, is there any tutorial that can be used for CPLEX 12.8?

@Zahidah Mohd Zaulir , @mateusarakawa is correct. Cplex’s multi objective feature is released in 12.9, for which you need to use AIMMS version 4.65.1 or above.
Your academic license will let you all the versions.
If you want to use CPLEX 12.8 for multi objective optimization, then you have to model it yourself using the different techniques available (a penalty based approach to build one final objective, solve the first problem, fix solution and then solve the second problem and so on). You cannot use the gmp::column::Setasmultiobjective function.
