I am a co-founder of VectorOptimizationGroup, a GitHub organization focused on software for multiobjective/vector optimization.

Co-founders: L. F. Prudente, Pedro Assuncao Filho

Solvers for multiobjective optimization.

Curated multiobjective benchmark problems with a consistent evaluation API, analytical derivatives for supported problems, and catalog queries.

Status: Registered in Julia's General registry. Install with Pkg.add("MultiObjectiveProblems").

Reusable multiobjective line searches, extracted from MOSolvers.jl, including Armijo-type backtracking with safeguarded quadratic interpolation.

Status: Public and documented; not yet registered in General. Install from the GitHub URL.

Metrics and evaluation utilities for multiobjective optimization experiments.

Status: Currently private while under development.
