Hello,

I am very new to Julia and JuMP. I am using CPLEX 12.8 together with my optimization problem.

Instead of using self-defined time function to capture the total time spent in the optimization process, is there a direct way to print out the total time (root+branch-and-cut) of CPLEX?

I try to use SolveTime() in MathOptInterface (v0.8.4) but it didn’t work.

When I typed MathOptInterface.SolveTime(), the result just give me

MathOptInterface.SolveTime().

And when I typed MathOptInterface.SolveTime(problem1), the error said

MethodError: no method matching MathOptInterface.SolveTime(::Model)

Closest candidates are:

MathOptInterface.SolveTime() at path

It would be nice if someone can show me how to correctly use the code since I also need to get the information of relative gap as well.

Thank you so much.
