In many industrial applications the need for an efficient and high-quality reconstruction of free-form surfaces does exist. Surface Reconstruction - the generation of CAD models from physical objects - has become an independent area of research. The supplementary modification and the automated manufacturing of workpieces represent typical fields of… (More)

An overview of the state-of-the-art in parallel evolutionary multiobjective optimization with a special view on the population structures is presented. An introduction to the theory of hypergraphs is given. The idea of hypergraphs is to scale freely between all existing population structures from coarse-grained island-models to fine-grained diffusionmodels.… (More)

We construct self-similar functions and linear operators to deduce a self-similar variant of the Laplacian operator and of the D'Alembertian wave operator. The exigence of self-similarity as a symmetry property requires the introduction of nonlocal particle-particle interactions. We derive a self-similar linear wave operator describing the dynamics of a… (More)

It is now increasingly realized that the underlying mechanism which governs aging (ageing) is a complex interplay of genetic regulation and damage-accumulation. “Aging as a result of accumulation of „faults‟ on cellular and molecular levels”, has been proposed in the damage (fault)-accumulation theory. However, this theory fails to explain some aging… (More)

This poster presents an evolution strategy for single- and multi-objective optimization. The model uses the predator-prey approach from ecology to scale between both cases. Furthermore the main issue of adaptation working for single- and multi-objective problem-instances equally is discussed. Particular, the well proved self-adaptation mechanism for the… (More)

We recently introduced Misrepair-accumulation theory as an interpretation on aging mechanism. For better understanding this theory, we discuss here in more details the new concept of Misrepair and the concept of accumulation of Misrepairs. I. Aging takes place uniquely on the systems that have a well-defined structure: an organization of its substructures.… (More)

We analyze the “fractional continuum limit” and its generalization to n dimensions of a self-similar discrete spring model which we introduced recently [21]. Application of Hamilton’s (variational) principle determines in rigerous manner a self-similar and as consequence non-local Laplacian operator. In the fractional continuum limit the discrete… (More)

Aging changes including age spots and atherosclerotic plaques develop in a manner of inhomogeneous and accelerated. For understanding this phenomenon, development of aging changes is analyzed by Misrepair mechanism, which is introduced in Misrepair-accumulation theory. I. Misrepair is a strategy of repair for increasing the surviving chance of an organism… (More)

Development of a tumor is known to be a result of accumulation of DNA mutations in somatic cells. However, the processes of how DNA mutations are produced and how DNA mutations accumulate in somatic cells are not completely known. There are several types of DNA mutations; however point mutations are the main type of mutations that can remain and accumulate… (More)
