Abstract: In this paper we describe iNEOS, an Internet-based environment which facilitates the solution of complex nonlinear optimization problems. It enables a user to easily invoke a remote optimization code without having to supply the model to be optimized. An interactive communication between client and server is established and maintainted using CORBA. We test the system in a simulation designed to identify material parameters of a piezoelectric crystal.

Keywords: nonlinear optimization, client-server, ASP, NEOS, BFGS, piezo-electric crystal
