is there any way to force CPLEX to add all user cuts (i.e., passing the option
Here https://github.com/JuliaOpt/CPLEX.jl/blob/master/src/cpx_callbacks.jl the option seems to be hard-coded to
CPX_USECUT_PURGE, but I want to avoid changing the parameter in the source code of the package.
Thank you in advance!!
I now changed the parameters manually in the source to
CPX_USECUT_FORCE at line 62/65 in the
cpx_callbacks.jl but this did not solve my problem:
I have an ILP model in which I use lazy and user callbacks and I want to add user cuts as long as I find some before branching starts. In particular I am interested in the root relaxation. In an minimal instance there are 3 user cuts. However, the user callback is only called once and therefore the last two cuts are not added.
