In the last few years, a significant number of multi-objective metaheuristics have been proposed in the literature in order to address real-world problems. Local search methods play a major role in many of these metaheuristic procedures. In this paper, we adapt a recent and popular indicator-based selection method proposed by Zitzler and Künzli in 2004, in order to define a population-based mul...

the objective of this study is to measure the city of tehran’s environmental quality in 2006 (the last census year). primarily, with a comparative analysis of a variety of urban sustainability indicator models, a collection of 54 indicators have been chosen and categorized as indicators of increase or decrease in urban environmental quality in the form of a simple mathematical model. based on t...

Complex situations of today's life have led to the complexity of urban life issues and not pay attention to the quality of life. Studies in this field are increasingly gaining the attention of urban planners and policymakers due to its usefulness in assessing and monitoring public policies, also they can use as effective tools in urban management and planning. This study investigated the QOL in...

During the past two decades, a variety of multiobjective evolutionary algorithms (MOEAs) have been proposed in the literature. As pointed out in some recent studies, however, the performance of an MOEA can strongly depend on the Pareto front shape of the problem to be solved, whereas most existing MOEAs show poor versatility on problems with different shapes of Pareto fronts. To address this is...

In this study a Multi-Objective Evolutionary System is used to predict the future tendency of assets price. Therefore, a framework using a Multi-Objective Genetic Algorithm (GA) in its core to optimize a set of Trading or Investment Strategies (TSs) was developed. The investigated framework is used to determine potential buy, sell or hold conditions in stock markets, aiming to yield high return...

In the field of evolutionary multi-criterion optimization, the hypervolume indicator is the only single set quality measure that is known to be strictly monotonic with regard to Pareto dominance: whenever a Pareto set approximation entirely dominates another one, then the indicator value of the dominant set will also be better. This property is of high interest and relevance for problems involv...

Chlorpropamide alcohol flushing (CPAF) in non-insulin-dependent diabetics (NIDDs) has been reported to be associated with a lower tendency to develop late complications. The flush was thought to be mediated by enkephalins and prostaglandins. Early studies could not correlate CPAF to increased levels of acetaldehyde in blood and the flush was not regarded as an antabuse-like reaction. In this st...

Real-world optimization problems are often subject to uncertainties, which can arise regarding stochastic model parameters, objective functions and decision variables. These uncertainties can take different forms in terms of distribution, bound and central tendency. In the multiobjective context, several studies have been proposed to take uncertainty into account, and most of them propose an ex...
