Optimal design of large-scale structures is a rather difficult task and the computational efficiency of the currently available methods needs to be improved. In view of this, the paper presents a modified Charged System Search (CSS) algorithm. The new methodology is based on the combination of CSS and Particle Swarm Optimizer. In addition, in order to improve optimization search, the sequence o...

since the third and fourth centuries ah, “the theory of moderation” which has greek origination and is based on aristotle's ideas in ethics, gradually entered islamic ethical literature and many scholars, such as ibnmiskawayhand khawajehnasir al-din tusi, found their ethical works on this idea. according to this theory, the virtue is complying with “the mean” in every action and avoiding t...

This paper shows how genetic programming (GP) can help in nd-ing generalizing Boolean functions when only a small part of the function values are given. The selection pressure favours functions having as few subfunctions as possible while only using essential variables, so the resulting functions should have good generalization properties. For eeciency no S-expressions are used for representati...

In Rethinking the Good, Larry Temkin argues for a principle that he calls the Narrow PersonAffecting View. In its simplest formulation, this principle states that a first outcome can be better than a second outcome only if there is someone who fares better in the first outcome than in the second. Temkin argues that this kind of principle gives us reason to reject the Transitivity Thesis, accord...

Restricted-orientation convexity is the study of geometric objects whose intersection with lines from some fixed set is empty or connected. We have studied the properties of restricted-orientation convex sets and demonstrated that this notion is a generalization of standard convexity. We now describe a restricted-orientation generalization of halfspaces and explore properties of these generaliz...
