Hello,
When I try to obtain in the MIP the relative gap and number of nodes, it gave me error:

gap_info = MOI.get(model, MOI.RelativeGap())
Num_nodes = MOI.get(model, MOI.NodeCount())

The error message is

MethodError: no method matching get_relative_mip_gap(::CPLEX.Optimizer)
Closest candidates are:
get_relative_mip_gap(!Matched::LinQuadOptInterface.MockLinQuadOptimizer) at

However, I used the same code to retrieve ObjectiveBound() and CPU time it works. It seems like some of the attributes are not working. Could you give me some insight about why would this happen or to implement in CPLEX.jl in a new version?
Thank you.

Hi @angeloaliano,

Welcome to CPLEX.jl!

or to implement in CPLEX.jl in a new version?

The steps to get this resolved are

  • Open a Julia REPL
  • Run ] dev CPLEX
  • Open ~/.julia/dev/CPLEX/src/MOI_wrapper.jl
  • Add the following function to that file
function LQOI.get_relative_mip_gap(model::Optimizer)
    return get_rel_gap(model.inner)
end

Let me know if you get stuck on any steps (I haven't for example, tested that the function works because I don't have CPLEX).

I can not to remove it, because I don't have permission (in the pencil, say that I must to be a branch)

You should remove it in the file: ~/.julia/dev/CPLEX/test/MathOptInterface/MOI_wrapper.jl in your computer (and also remove the comma in the previous line).

Dear,
I tried to perform the changes in the archives, as you attached.
I

n the ~.julia\packages\CPLEX\mo9kV\src\MOI_wrapper and in ~.julia\packages\CPLEX\mo9kV\test\MathOptInterface. But, when I run ] test CPLEX, a error message appears.
Also, I changed the archive in https://github.com/JuliaOpt/CPLEX.jl/blob/master/src/MOI_wrapper.jl, inserting the function
function LQOI.get_relative_mip_gap(model::Optimizer)
return get_rel_gap(model.inner)
end.
There is anything to I do yet?
Would you like to help me please?

We cannot see the errors, can you scroll up and give a screenshot of the error messages ? Or just copy-paste them

One problem (that is not your fault) is linear10b. To fix, change line 29 to
"linear10", "linear10b", # requires interval

Dear all,
I made the corrections as above. But, when I run ] text CPLEX, the error appear yet. Follow the error messages.
