Add a sampling scheme that makes it easy to write a model of a Markov chain (e.g., in price), and then simulate it using some true distribution, that jumps to...
The upcoming release of JuMP v1.2 will break EAGO. Read more here: https://discourse.julialang.org/t/ann-upcoming-refactoring-of-jumps-nonlinear-api/83052 This will affect EAGO because you rely on a lot of internal features that are being deleted:...
The tutorials use this `DATA_DIR` variable which is hidden https://github.com/NREL-SIIP/PowerSystems.jl/blob/eab51ddf29d6d37f62b0c2f160bc7bd632bacee2/docs/src/modeler_guide/modeling_with_JuMP.jl#L20-L21 That makes it a bit confusing I assume what's missing in the general ``` using PowerSystems DATA_DIR = download(PowerSystems.UtilsData.TestData, folder...

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.
Unresolved TODO from #261 https://github.com/JuliaOpt/CPLEX.jl/blob/7c4acf18e78e360bb4691fe97b47d2e98d6d29c8/test/MathOptInterface/MOI_wrapper.jl#L48-L50
@adow031 has seen an example where Gurobi solves a QCP, experiences numerical error and fails to return the duals, but `DualStatus` is `FEASIBLE_POINT`. The error is ```Julia Barrier performed 54...
