BOOSTERS: a derivative-free algorithm based on radial basis functions

Derivative-free optimization involves the methods used to minimize an expensive objective functionwhen its derivatives are not available. We present here a trust-region algorithmbased on Radial Basis Functions (RBFs). The main originality of our approach i ...

A new derivative-free algorithm for the medical image registration problem

Michel Bierlaire, Rodrigue Oeuvray

The medical image registration problem can be formulated as a nonlinear programming problem. To identify appropriate algorithms to solve it, it is critical to analyze the properties of the problem. In this paper, we consider the image registration problem ...
