Query: Parallel Strategies for Direct Multisearch   Direct Multisearch (DMS) is a Derivative-free Optimization class of
algorithms suited for computing approximations to the complete Pareto front of
a given Multiobjective Optimization problem. It has a well-supported
convergence analysis and simple implementations present a good numerical
performance, both in academic test sets and in real applications. Recently,
this numerical performance was improved with the definition of a search step
based on the minimization of quadratic polynomial models, corresponding to the
algorithm BoostDMS.
  In this work, we propose and numerically evaluate the performance of
parallelization strategies for this solver, applied to the search and to the
poll steps. The final parallelized version not only considerably decreases the
computational time required for solving a Multiobjective Optimization problem,
but also increases the quality of the computed approximation to the Pareto
front. Extensive numerical results will be reported in an academic test set and
in a chemical engineering application.
