Hello,

I try to print the solution of my optimization model. Currently, I receive a big file with all the values from my decision variables with: 

if ModelA.status == GRB.OPTIMAL:
    ModelA.write('ModelA.sol')

but I want to see only the decision variables which are equal or greater one. Maybe someone has an idea :)

The decision variables in my model are: two binary, one continuous

(It is not necessary to create an additional file. It is enough to print the solution)

Thanks in advance

  ModelA.printAttr('X') prints all non-zero solution values.
