查询词典 evolutionary

Eubacteria A major subkingdom of the Bacteria, containing a large and diverse group of bacteria, principally distinguishable from the other major subkingdom, the Archaea, by differences in the base sequences of RNA subunits of the very early evolutionary divergence between the two groups.

真细菌：细菌门的一个主要亚界，该类细菌种类繁多，形态各异，大体上可区别于其它亚界。因 RNA 亚单位的基本序列的不同而主要的区别于古细菌，这种不同反映了这两组细菌早期的进化趋异。

At least one suborder of trilobites, the Agnostina , are thought to be primarily eyeless . None have ever been found with eyes. In contrast, a few secondarily eyeless species (in which a clear evolutionary trend toward reduced eye size with eventual disappearence of eyes altogether) have developed within several groups, even those known for large, well-developed eyes ( e.g., Phacopina).

在最少一个亚目的三叶虫 Agnostina 中，通常是盲目的，这类三叶虫从来没有发现过眼睛的构造，以此相对的，一些很少的其他亚盲目的种（一些进化了简单的眼睛的物种）是比较进化的，甚至是一些大个体的，有很好的眼睛发育的种，如 Phacopina。

And it will assist in revealing the adaptive evolutionary mechanism of visual system of subterranean rodents.

因此，这为地下啮齿动物视觉系统进化提供了理想的研究材料，将对地下啮齿动物视觉系统适应进化机制的研究起积极促进作用。

Combining the shortcoming of multi-objective evolutionary algorithm based on the idea of objective space dividing with high calculation complexicity, this paper proposed an improved new algorithm which processed following characters: transforming the dominance relationship among individuals' Pareto to the rank relationship of sum index of interval in dividing space; simple and efficient environmental choosing method based on index ranking; an individual crowding algorithm which rapidly choosing the nearest to origin.

针对现有基于目标空间分割思想的进化算法计算时间复杂度高的缺陷，提出了一种改进的基于目标空间分割的多目标进化算法。该算法具有以下特点：把个体之间的Pareto支配关系转换成分割区间索引值排序关系的目标空间分割算法；简单高效的基于区间索引值排序的环境选择算子；一种快速的优先选择最接近分割区间原点的个体拥挤机制。

The evolutionary game theory has been used by more and more economists and sociologists to explain and predict the behavior of groups of the participated people.So this method can effectively fill the existing closed-loop supply chain theory of the lack of research as a closed-loop supply chain,and as a new method of coordination.

而演化博弈理论这种被越来越多经济学家和社会学家应用于解释、预测参与人群体行为的经济学理论方法，可以有效弥补现有闭环供应链理论的不足，作为研究闭环供应链协调的新方法。

Evolutionary biologists tend to be atheists, and most would be surprised if the scientific investigation of religion did not end up supporting their point of view.

进化生物学家们通常是无神论者，如果对宗教进行的科学研究结果最终与他们观点不相吻合，他们肯定会惊叹不已。

In addition to its ties with A-life, particle swarm optimization has obvious ties with evolutionary computation.

除了它的联系，以生活，粒子群优化具有明显的关系，进化计算。

Particle Swarm Optimization Algorithm with Organization is an evolutionary algorithm based on population intelligence and exhibits good performance on optimization.

提出了带组织的粒子群优化算法。粒子群优化算法是一种基于群体智能的演化算法，具有良好的优化性能。

To overcome the difficulties and drawbacks in modeling the dynamic systems by using traditional methods, a hybrid evolutionary modeling algorithm is proposed to model the dynamic system with a system of ordinary differential equations whose main idea is to embed genetic algorithm in genetic programming where GP is employed to optimize the structure of a model, and GA is employed to optimize the parameters of a model.

针对采用传统方法解决动态系统的微分方程建模问题所遇到的困难和存在的不足，文中设计了将遗传程序设计与遗传算法相嵌套的混合演化建模算法，以遗传程序设计优化模型结构，以遗传算法优化模型参数，成功地实现了动态系统的常微分方程组建模过程自动化。
