I am wondering if it is possible to use CPLEX.jl to annotate models to implement the CPLEX benders decomposition (see https://www.ibm.com/support/knowledgecenter/SSSA5P_12.8.0/ilog.odms.cplex.help/CPL…

Currently, the function `enable_parameters` only takes JuMP.Models. In order to be able to have sub-problems with Parameters in a StructJuMP `StructuredModel` this function would have to accept any su…

Hi, Martin
I have used StochasticPrograms to solve my model, However,there is a warning:
```
┌ Warning: First-stage has binary/integer decisions and no `IntegerStrategy` has been set. Procedur…

Hi,
My stochastic model converges easily to the optimal solution when using the deterministic equivalent formulation. Nevertheless, PH and L-Shaped methods do not converge at all (see title). I have…

Hi,
I'm using CPLEX with Julia for optimization. I'm trying to change the CPLEX parameters for it to optimize with benders decomposition instead of Branch and Bound with is the default method. I h…
