vOptSolver is aimed to be a software for scientifics and practionners. It has been conceived to be intuitive for various profile of users (mathematicians, informaticians, and engineers), corresponding to needs encountered in research and development (open-source codes available for the design of new algorithms), decision-making (ready-to-use methods and algorithms for solving optimization problems), and education (environment for teachning and practicing the theories and algorithms).

The optimization problem to solve is built in formulating a model with the algebraic modeling language JuMP, extended to support multi-objective models, for non-structured optimization problems, or in calling the corresponding API for structured optimization problems. The problem data and the optimization results are set on and handled by the datastructures and functionalities of Julia.

vOptSolver integrates several generic and specific algorithms of the literature for computing the set of exact non-dominated points. It returns also the efficient solutions corresponding to this set. The generic algorithms make use of a MIP solver, while specific algorithms call problem-dedicated algorithms.
