@kofgokhan it looks like there's a bug in DominguezRios. It doesn't terminate on this problem (it gets into an infinite loop):
using Revise
import HiGHS
import MultiObjectiveAlgorithms as MOA
import MultiObjectiveAlgorithms: MOI
include("test/vOptLib.jl")
model = MOA.Optimizer(HiGHS.Optimizer)
MOI.set(model, MOA.Algorithm(), MOA.DominguezRios())
MOI.set(model, MOI.Silent(), true)
MOI.set(model, MOI.TimeLimitSec(), 60.0)
vOptLib.test_vOptLib_2KP50_11(model)

I could not replicate this on my machine. It returns 43 points. Used both HiGHS and CPLEX and I have not changed the tolerances. Did something change?
> model = MOA.Optimizer(HiGHS.Optimizer)
> MOI.get(model, MOI.RawOptimizerAttribute("primal_feasibility_tolerance"))
1.0e-7
> model = MOA.Optimizer(CPLEX.Optimizer)
> MOI.get(model, MOI.RawOptimizerAttribute("CPX_PARAM_EPRHS"))
1.0e-6

My conclusion in #121 is that it's a presolve issue in HiGHS. If you can't replicate, then it probably means that it's machine dependent too :(
