Abstract
The ALOPEX process was developed in the early 70's by Harth
and Tzanakou as an automated method of mapping Visual Receptive Fields
in the Visual Pathway of animals. Since then it has been used as a
"universal" optimization method that lends itself to a number of
optimization problems.
The method uses a cost function that is calculated by the simultaneous
convergence of a large number of parameters. It is iterative and
stochastic in nature and has the tendency to avoid local extrema.
Computing times largely depend on the number of iterations required for
convergence and on times required to compute the cost function. As such
they are problem dependent. On the other hand ALOPEX has a unique
inherent feature i.e it can run in a parallel manner by which the
computing times can be reduced.
Several applications of the method in physical, physiological and
pattern recognition problems will be discussed.
