In optimization, multiple objectives and constraints cannot be handled independently of the underlying optimizer. Requirements such as continuity and di erentiability of the cost surface add yet another con icting element to the decision process. While \better" solutions should be rated higher than \worse" ones, the resulting cost landscape must also comply with such requirements. Evolutionary ...

In this technical report we define an operational net semantics for the stochastic process algebra MPA based on generalized stochastic Petri nets. As a consequence of the definition of such a semantics, we present an interesting modeling technique for concurrent systems which is based on MPA. 1.

In radar HRRP target recognition, the quality and quantity of Discriminant Information (DI), which one is more important? Accompanied with this issue, the paper proceeds to delve into DI analysis, and accordingly, three fundamental DI extraction models are proposed, i.e., PGA, PIB and AIB. Among these models, PIB and AIB both aim to obtain Between-class DI (B-DI) from individual standpoints whi...

We consider the (minimal) distance function of a point in the plane to a set P of N points in the plane. The locus of non-di erentiability of this distance function consists (besides of the points of P) exactly of the Voronoi diagram of P. We show that the number of minima (m), maxima (M) and `saddle points' (s) of the distance function satisfy: m s +M = 1 This is similar to the Morse type of s...

Jonathan M. Borwein1, Xianfu Wang August 13, 1999 ABSTRACT. We prove a \typi al" subdi erentiability prin iple and apply it to a variety of omplete metri spa es of ontinuous fun tions on separable Bana h spa es; so as to obtain existen e of fun tions with maximal subdi erentials when ordered by in lusion. The relationship between ontinuous fun tions with maximal subdi erentials and nowhere mono...

In this paper, the general class of morphological/rank/linear (MRL) multilayer feed-forward neural networks (NNs) is presented as a unifying signal processing tool that incorporates the properties of multilayer perceptrons (MLPs) and morphological/rank neural networks (MRNNs). The fundamental processing unit of MRL-NNs is the MRL-"lter, where the combination of inputs in every node is formed by...

Koblenz, Germany, October 1997 How CAS and Visualization lead to a Complete Rethinking of an Introduction to Vector Calculus Matthias Kawski1 Arizona State University [email protected] http://math.la.asu.edu/~kawski Abstract. This article demonstrates how newly available technology suggests to completely rethink how key concepts of (vector-) calculus are introduced. We consider this a particularly...
