查询词典 evolutionary

Combining with co-evolution mechanism, we renewedly defined the several aspect of the co-evolutionary agent, such as the belief, action, communication, decision maker, and so on. We made the co-evolutionary agent model and actual world model become a uniform closed loop system, and established the symbol deduction theory model of multi-agent system based on co-evolution mechanism.

结合协进化机制，从符号演绎逻辑的角度重新定义了协进化智能体的信念、动作、通信、决策器等各个方面，将协进化智能体模型与实际世界模型形成一个统一的闭环系统，并建立了基于协进化的多智能体系统的符号演绎理论模型。

By introducing the real valued code, deteminstic crowding niching algorithm, improving the genetic algorithm, we present an evolutionary algorithm that generates Hypercube detector - Deviation Levels based Detection Algorithm and an evolutionary algorithm that generates fuzzy rule detectors - Fuzzy Rules based Anomaly Detection Algorithm.

通过引入实数编码，精确排挤小生态算法，对遗传算法进行改进，研究了基于背离等级的检测算法(Deviation Levels based Detection Algorithm，简称DLDA)，同时为了提高检测的准确性，引入了一种生成模糊检测规则的演进算法，使用模糊异常检测算法，对网络中的异常行为进行模糊检测。

Barash writes,"However, stimulated by the Lightman-Gingerich thesis, I have reviewed numerous pre-1964 textbooks of animal behavior and evolutionary biology and have discovered that, in fact -- and contrary to my own above-cited assertion -- before Hamilton's insight, evolutionary biologists were not very much troubled by the occurrence of apparently altruistic behavior among animals (at least they did not devote much theoretical or empirical attention to the phenomenon)."

Barash写道，&出于Lightman-Gingerich论文的激励，我当时回顾了大量1964年以前的有关动物行为和进化生物学方面的教科书，却发现事实上――和我上面所引的相反――在Hamilton之前，进化生物学家们并不很在意动物界频发的明显利他行为（至少对此现象他们没有投入精力做些理论探究或报以实际的考察关注）。&

WASHINGTON - Scientists unearthed a skull of the most primitive four-legged creature in Earth's history, which should help them better understand the evolution of fish to advanced animals that walk on land. The 365 million-year-old fossil skull, shoulders and part of the pelvis of the water-dweller, Ventastega curonica, were found in Latvia, researchers report in a study published in Thursday's issue of the journal Nature. Even though Ventastega is likely an evolutionary dead-end, the finding sheds new details on the evolutionary transition from fish to tetrapods. Tetrapods are animals with four limbs and include such descendants as amphibians, birds and mammals.

华盛顿-科学家挖掘出一副地球历史上最原始的四足生物头骨，这个有利于帮组他们更好理解鱼类进化成为更先进的陆地行走生物，这个有着三亿六千五百万年年龄的头骨，肩膀和水生生物的一部分骨盆，Ventastega curonica，在Latvia被发现，研究者一篇研究报告发表在在星期三出版的自然杂志上，尽管Ventastega 可能是一个进化的死胡同，这个发现给出了从鱼类到四足动物进化变迁过程的新细节，四足动物是使用四肢的动物并且包括下属的比如两栖类动物，鸟类和哺乳类动物。
