Embedding the gradient direction search and new kinds of evaluation functions into the Genetic Algorithm, a special hybrid Genetic Algorithm with mutation along the weighted gradient direction to solve non-linear programming problems is developed. Then in Chapt 4, a type of nonlinear programming problems with fuzzy objective and fuzzy resources constraints is discussed, in which the objective is ill-defined and the resources possess two different types of fuzzy resources, i. e., tolerance and imprecision. By way of description and formulation of fuzzy objective and fuzzy resources, the problem with fuzzy objective and two different types of fuzzy resources is modelled into a fuzzy nonlinear programming model FO/RNLP and interpreted as three equivalent alternative crisp model to reflect the variety of the environment and the subjective and preference of the decision maker .

本文首先针对遗传算法在求解非线性规划问题中存在的问题,首次提出非可行点/染色体的主导准可行方向,准可行方向,及非可行点属于可行域的可行度等新概念,借助于模糊思想,提出了描述和度量非可行染色体的新方法;通过嵌入非可行染色体的信息于评价函数中,提出了三种新的评价非可行染色体的评价函数;把传统的启发式方法-梯度方向搜索和新的评价函数嵌入到遗传算法中,提出了一种沿加权梯度方向变异的新型混合式遗传算法;第四章针对生产实际中非清晰定义的模糊目标和两种类型的模糊资源,建立了一类连续型模糊目标/资源约束非线性规划问题的模型FO/RNLP。

The first half of the chapter begins with the introduction of three common viewpoints over the two kinds of theories, followed by deep investigation and description of some biased nature in them, then comes up with the conclusion that we must draw a clear distinction between what was said by Marx himself and what has long been accepted as dogmatical statements. The later half of chapter introduces various understandings to the theory of three social orders evoked by the discussion of economic social formation, points out the drawbacks of and the author"s disproval to the idea that economic social formation only exists in a definite historical period. This chapter is to deepen the understanding of Marx" theory of three social orders through the discussion of the other two important theories related to it.

首先介绍了迄今为止在&三形态说&和&五形态说&的讨论中出现的三种基本观点,并分别对这些观点加以反思,通过反思指出了这几种观点中存在的一些偏颇之处,提出了在讨论三大社会形态理论和五种社会形态理论的相互关系时要对马克思本人的&五形态说&和传统的教条化的&五形态说&加以明确的区分;接着介绍了在讨论&经济的社会形态&这一范畴时所引发的对三大社会形态理论的不同理解,指出了把&经济的社会形态&理解为一种特定历史阶段的社会形态类型所产生的问题,反对把&经济的社会形态&理解为一种特定历史阶段的社会形态类型。
