The model was implemented in C#. We chose the Cplex 12.12 solver to maximize our model.

1. We create similarity matrix.

2. We compute the similarity values

3. We compute the constants

4. We create the matching variables

5. We create the objective function

6. We create the constraints

See the code below . It is not all the code but we focus on the important parts

The full source code is available on my gitlab : https://gitlab.com/romain.raveaux/a-single-model-for-ged-and-gm

That's it !!!
The model is made.
