Two of Pareto Distribution Family have often be...

Pareto分布族中的两个分布已被列入精算师常用的八大分布之中，由此可见Pareto分布族的实际应用价值，也说明了我们对Pareto分布族研究的重要意义。

With the development of society, Pareto distribution has been improved and extended to several kinds of Pareto distribution, which formed Pareto Distribution Family.

随着时间的推移、社会的发展，Pareto分布也在不断地完善、改进、推广，从而形成了多种形式的Pareto分布、广义Pareto分布乃至Pareto分布族。

Multiobjective optimization problem has a wide range of applications in the real world. It is different from the single objective optimization. It often involves incommensurable and competing objectives, and the number of its Pareto optimal solutions is usually infinite. Therefore, it is very important to design new algorithms which can find well distributed and close-to-Pareto-optimal solutions.

在现实世界中很多问题都是多目标优化问题，不同于单目标优化，在多目标优化中，各目标之间是互相冲突的，其最优解往往有无穷多个，如何使得到的Pareto最优曲面距离真正的Pareto最优曲面最近、最优解的分布均匀且范围更广是求解多目标优化问题的关键。

After analyzing the properties related to the Pareto optimum security strategy of fuzzy multi-goals, an approach to the solution of Pareto strategy is proposed.

在分析模糊多目标Pareto策略性质的基础上，提出了该策略的确定方法。

The algorithm of multi-objective fuzzy shoretest path and Pareto solution space are discussed, and a method based on fuzzy inference engine is presented to select multiple Pareto solution.

讨论了多目标模糊最短路径的算法与Pareto解空间问题，提出了基於模糊推理引擎选择多个Pareto解的策略。

Based on the study of a Pareto optimal for multiobjective optimizations , the Genetic algorithms for MOP is studied. Four new operators are introduced into this MGA that are niche technique, Pareto optimal set, nondominated rank and fuzzy penalty function method.

在研究多目标优化有效解集的基础上，对处理多目标优化的遗传算法进行研究，引入小生境技术、Pareto过滤解集，给出了非劣解排序的方法；对小生境技术引入的优越性进行了比较研究，通过算例检验了本文研究的多目标遗传算法的有效性。

The improved Pareto multi-objective optimization with GA adopts non-dominated ranking, elitist preserve and niche approaches, and proposes individual vector module adaptive function as wash out rule. As an example, two duality functions are used to validate the two algorithms.

通过两个多元函数的最小值优化算例验证，两种方法均获得较为均匀分布的Pareto前沿，并且改进的Pareto遗传多目标优化算法由于采用了小生境技术，使得最优解的分布更加均匀，避免了局部收敛的问题。

He named it the parietal perusable "Pareto principle", for the Italian economist Frito Prato Vilfredo Pareto . A century ago, Prato Pareto observed that eighty percent of wealth in Italy went to twenty percent of the population.

他命名为&Pareto原理&，为了纪念意大利经济学家Vilfredo Pareto.1个世纪前，Pareto观察到意大利80％的财富在20％的人手中。

The NPMOGA algorithm based on non-penalty parameter constraints solving method is composed of the niched Pareto genetic algorithm and non-penalty parameter constraints solving method.

基于无罚系数约束处理方法的NPMOGA算法，由基于Pareto竞争和等价类共享的小生境Pareto遗传算法和无罚系数的约束处理方法组成。
