Constrained and unconstrained Nonlinear Optimization
Problems often appear in many engineering areas.
In some of these cases it is not possible to use derivative
based optimization methods because the objective function is
not known or it is too complex or the objective function is
non-smooth. In these cases derivative based methods cannot be
used and Direct Search Methods might be the most suitable
optimization methods. An Application Programming Interface
(API) including some of these methods was implemented
using Java Technology. This API can be accessed either by
applications running in the same computer where it is installed
or, it can be remotely accessed through a LAN or the Internet,
using webservices. From the engineering point of view, the
information needed from the API is the solution for the
provided problem. On the other hand, from the optimization
methods researchers’ point of view, not only the solution for
the problem is needed. Also additional information about the
iterative process is useful, such as: the number of iterations;
the value of the solution at each iteration; the stopping criteria,
etc. In this paper are presented the features added to the API
to allow users to access to the iterative process data.
