So, in the SCIP package, there seems to be an issue in this file "quadratic_constraints.jl". Particularly, lines 190-192 in the below function. The SCIP solver generates a solution, but it...

Hi, is it possible to add support for `optimizer_attribute` to collect all feasible solutions: `set_optimizer_attribute(model, "constraints/countsols/collect", 1)` The question appeared on discourse and it seems SCIP is the only free...

Hello, I am trying to use SCIP with MultipleObjectiveAlgorithms.jl `Model(()->MOA.Optimizer(SCIP.Optimizer))`, but at some point optimization terminates with the following error: `SCIP is wrong stage (SCIP_STAGE_PROBLEM, need (SCIP.LibSCIP.SCIP_STAGE_PRESOLVING, SCIP.LibSCIP.SCIP_STAGE_SOLVING, SCIP.LibSCIP.SCIP_STAGE_PRESOLVED, SCIP.LibSCIP.SCIP_STAGE_SOLVED))!`
