Problem Topology, Texture and Objectives
نویسنده
چکیده
We propose a model of problem solving that provides both structure and focus to search. The model achieves this by combining constraint satisfaction with heuristic search. We introduce the concepts of topology and texture to characterize problem structure and areas to focus attention respectively. The resulting model reduces search complexity and provides a more principled explanation of the nature and power of heuristics in problem solving. This research has been supported, in part, by the Defense Advance Projects Agency under contract #F30602-88-C-0001, and in part, by grants from McDonnell Aircraft Company, Boeing Computer Services, and Schlumberger Corp.

GRADED DIUNIFORMITIES
Graded ditopological texture spaces have been presented and discussed in categorical aspects by Lawrence M. Brown and Alexander {v S}ostak in cite{BS}. In this paper, the authors generalize the structure of diuniformity in ditopological texture spaces defined in cite{OB} to the graded ditopological texture spaces and investigate graded ditopologies generated by graded diuniformities. The autors...
متن کاملCategories of fuzzy topology in the context of graded ditopologies on textures
This paper extends the notion of ditopology to the case where openness and closedness are given in terms of {em a priori} unrelated Drading functions. The resulting notion of graded ditopology is considered both in the setting of lattices and in that textures, the relation between the two approaches being discussed in detail. Interrelations between graded ditopologies and ditopologies on textur...
متن کاملConcept of Skeleton Texture Mapping
This article introduces an idea for novel way of mapping textures onto a surface of 3D model. Our technique is based on two interlocking mappings, the first one maps surface vertices onto computed skeleton and the second maps surrounding area of each skeleton segment into a rectangle with dimensions based on surface properties around this segment. Furthermore, these rectangles are packed into a...

متن کاملSOLVING MULTI CONSTRAINTS STRUCTURAL TOPOLOGY OPTIMIZATION PROBLEM WITH REFORMULATION OF LEVEL SET METHOD
Due to the favorable performance of structural topology optimization to create a proper understanding in the early stages of design, this issue is taken into consideration from the standpoint of research or industrial application in recent decades. Over the last three decades, several methods have been proposed for topology optimization. One of the methods that has been effectively used in stru...
