One of the most relevant problems in Bioinformaticsand Computational Biology is the search and reconstruction ofthe most accurate phylogenetic tree that explains, as exactly aspossible, the evolutionary relationships among species from agiven dataset. Dif... see more

Multiple Sequence Alignment (MSA) is one of the main topics in the bioinformatics domain, consists in ?nding an optimal alignment for three or more biological sequences with the number maximum of conserved zones or totally aligned columns. Different score... see more

Portfolio selection has been the subject of extensive studies in order to obtain increased returns, minimizing the investment risk. However, the most appropriate risk measure to be considered is still an open problem. The aim of this work is to study diff... see more

Evaluation of indeterminate forms is a current problem for a significant class of formalized system analysis tasks. Formally, the problems of indeterminate forms evaluation in the system analysis and the operations research theory are largely similar. How... see more

This paper deals with the multiobjective optimization problem of an agroalimentary production workshop. Three criteria are considered in addition to this initial cost of production: the cost of the out-of-date products, the cost of the distribution discou... see more

Interactive methods of multiobjective optimization repetitively derive Pareto optimal solutions based on decision maker's preference information and present the obtained solutions for his/her consideration. Some interactive methods save the obtained solut... see more

Portfolio management based on mean-variance portfolio optimization is subject to different sources of uncertainty. In addition to those related to the quality of parameter estimates used in the optimization process, investors face a portfolio implementati... see more

This study aimed to develop a building energy system design method to minimize the initial investment cost and primary energy use. As for the energy system, various combinations were generated depending on the type and capacity of the device used as well ... see more

Context. The problem of increasing the efficiency of optimization methods by synthesizing metaheuristics is considered. The objectof the research is the process of finding a solution to optimization problems.Objective. The goal of the work is to increase ... see more
