CPLEX Error 3003: Not a mixed-integer problem when calling relative_gap on a pure LP model

5

This is similar to #355. If all the variables of the JuMP model are continuous the model solves correctly but some post-solve methods might fail. Here, relative_gap() errors with CPLEX...

This line adds a new MIP start https://github.com/jump-dev/CPLEX.jl/blob/71e64ea78fea5dc83c556ee76df2b5ea1df124e4/src/MOI/MOI_wrapper.jl#L2458-L2469 Bit it _adds_ a mip-start, leaving the previous one in-place. Looks like we need to use https://www.ibm.com/support/knowledgecenter/SSSA5P_20.1.0/ilog.odms.cplex.help/refcallablelibrary/mipapi/getnummipstarts.html https://www.ibm.com/support/knowledgecenter/SSSA5P_20.1.0/ilog.odms.cplex.help/refcallablelibrary/mipapi/delmipstarts.html to delete existing ones.

I'm helping to develop a package (https://github.com/genXProject/genX) that can use CPLEX (through JuMP), and can also use other solvers. Not all users will have access to commercial solvers (and neither...
