‎a common approach to determine efficient solutions of a multiple objective optimization problem‎ ‎is reformulating it to a parameter dependent scalar optimization problem‎. ‎this reformulation is called scalarization approach‎. here, a well-known scalarization approach named pascoletti-serafini scalarization is considered‎. first, some difficulties of this scalarization are discussed and then ...

The topic of this paper are discrete decision problems with multiple criteria. We rst deene discrete multiple criteria decision problems and introduce a classiication scheme for multiple criteria optimization problems. To do so we use multiple criteria optimization classes. The main result is a characterization of the class of lexicographic max-ordering problems by two very useful properties, r...

The Extreme Point Deterministic Algorithm (EPDA), proposed for the multicriterion minimum spanning tree problem, is applicable to more than two criteria and can determine large Pareto fronts comprising of both supported and non-supported efficient solutions, unlike many existing algorithms. EPDA is validated against an exhaustive search for small problems (four to ten nodes, two and three crite...

A major problem associated with the reverse engineering of genetic networks from micro-array data is how to reliably 5nd genetic interactions when faced with a relatively small number of arrays compared to the number of genes. To cope with this dimensionality problem, it is imperative to employ additional (biological) knowledge about real genetic networks, such as limited connectivity, redundan...

this paper proposes a method to solve multi-objective problems using improved particle swarm optimization. we propose leader particles which guide other particles inside the problem domain. two techniques are suggested for selection and deletion of such particles to improve the optimal solutions. the first one is based on the mean of the m optimal particles and the second one is based on appoin...

It is well-known that fisheye cameras can be very useful in real applications due to their large field of view when compared to classic perspective cameras. This paper considers the fundamental problem of multiple-view triangulation for fisheye cameras. A geometric criterion is introduced in this paper for this problem, which consists of determining the scene point that minimizes the angles bet...

Users of media broadcasting services generally experience different grades of overall performance because of the non-uniform conditions of their channels. In order to provide all users equally satisfactory performance, we propose a new performance criterion named “minimax disappointment” (MD), based on layered service levels and the basic principle of joint source-channel coding [1]. This crite...

In this paper, we propose a novel approach for code acquisition in the code-division multiple access (CDMA) communication system. The essential assumption is that the pilot signal of the desired user is available. If the codes are exactly orthogonal, the method can be derived from an optimization criterion. Using the pilot signal, the performance can be greatly improved without increasing compu...

Many decisions involve multiple stages of choices and events. In this paper to develops fuzzy dynamic system approach for solving multistage decision-making problems. Fuzzy dynamic system is a promising tool for dealing with multistage decision-making and optimization problems under fuzziness. The cases of deterministic, stochastic, fuzzy dynamic system, fuzzy criterion set dynamic programming,...
