A derivative-free parallel algorithm for bound constrained programming problems

ABSTRACT
The paper is devoted to the study of synchronous and asynchronous parallel implementations of a line search derivative-free method for bound constrained nonlinear optimization. Both the methods are proved to be globally convergent toward a KKT point of the problem. The asynchronous method has been implemented using the message passing interface library and its performances have been compared to those of the sequential version on a difficult parameter estimation problem.
