With the growing reliability of modern ad hoc networks, it is encouraging to analyze potential involvement autonomous agents in critical situations where human could be perilous. One such scenario Search and Rescue effort event a disaster, which timely discovery help deployment utmost importance. This paper demonstrates applicability bio-inspired technique, namely Ant Algorithms (AA), optimizin...

Increasing economy’s resistance against the menace of sanctions, various risks, shocks, and internal and external threats are one of the main national policies which can be implemented through bank investments. Investment project selection is a complex and multi-criteria decision-making process that is influenced by multiple and often some conflicting objectives. This paper studies portfolio inve...

The problem of the sample variance computation for epistemic inter-val-valued data is, in general, NP-hard. Therefore, known efficient algorithms for computing variance require strong restrictions on admissible intervals like the no-subset property or heavy limitations on the number of possible intersections between intervals. A new asymptotic algorithm for computing the upper bound of the samp...

This technical report summarizes our results on solving graph coloring problems with Genetic Algorithms (GA). After testing many diierent options we conclude that the best one is a (1+1) order-based GA using an adaptation mechanism that periodically changes the tness function, thus guiding the GA through the search space. Except from the decoder ((tness function) this GA is general, using no do...

The paper is aimed at experimental evaluation of the complexity of the p-Median problem instances, defined by m × n costs matrices, from several of the most widely used libraries. The complexity is considered in terms of possible problem size reduction and preprocessing, irrespective of the solution algorithm. We use a pseudo-Boolean representation of PMP instances that allows several reduction...

background: radial movement of the arterial wall is a well-known indicator of the mechanical properties of arteries in arterial disease examinations. in the present study, two different motion estimation methods, based on the block-matching and maximum-gradient algorithms, were examined to extract the radial displacement of the carotid artery wall. methods: each program was separately implement...

this paper presents a biogeography-based optimization (bbo) algorithm to solve the economic loaddispatch (eld) problem with generator constraints in thermal plants. the applied method can solvethe eld problem with constraints like transmission losses, ramp rate limits, and prohibited operatingzones. biogeography is the science of the geographical distribution of biological species. the modelsof...
