查询词典 evolutionary

In the improved algorithm, two matrices describing the relation between transfer stations of all levels with angular points of grids and the relation between two adjacent levels' transfer stations were established to delete constraints and compress greatly variables of the model; an evolutionary algorithm based on evolutionary similarity was applied to mix the basic properties of global and local search; the self-adaptive delta variation operator, dual arithmetic crossover operator, peak-jump operator were used to improve the behaviors of artificial fish-swarm algorithm.

在算法中建立了各级中转站与网格点关系矩阵和相邻两级中转站间的关系矩阵来消除约束条件和压缩变量数；使用了基于相似性的演化算法来融合全局搜索和局部搜索；使用了自适应delta变异算子、双算术交叉算子、峰跳操作算子等多种算子改进人工鱼的各种行为。

"Because of its epochal scope, evolutionary biology is often caricatured as incompatible with controlled experimentation," says Losos, professor of organismic and evolutionary biology in Harvard's Faculty of Arts and Sciences and curator in herpetology at the Harvard Museum of Comparative Zoology.

"因为它的跨年代的时间尺度，进化生物学常常被讽刺为不适用于可以由控制性的实验来证明的学科。"

So it was appropriate that Svante Paabo of the Max Planck Institute for Evolutionary Anthropology, in Leipzig, chose Darwin's 200th anniversary to announce what would, until recently, have been thought an impossible discovery in evolutionary biology—a draft of the genome of Neanderthal man.

因此，位于莱比锡的马克斯·普朗克人类进化学院的施温提·柏保恰好在达尔文的200周年纪念日时，宣布了一项一直被认为是在进化生物学上不可能的发现——提取出了一个尼安德特人的基因组。

近来性能较为显著的基于PSO算法的改进算法有Thanmaya Peram[10]等人于2003年提出的基于粒子群优化的适应值-距离-比例算法(Fitness-Distance-Ratio based Particle Swarm Optimization， FDR-PSO)，在此算法中每个粒子根据一定的适应值-距离-比例原则，向附近具有较好适应值的多个粒子进行不同程度的靠近，而不仅仅只向当前所发现的最好粒子靠近。

In essence, this program asks a human to be the fitness function of an evolutionary algorithm, so that the algorithm can use human visual perception and aesthetic judgment to do something that a normal evolutionary algorithm cannot do.

从本质上说，这一计划要求将一个人的适应度函数的进化算法，因此，该算法可以利用人的视觉感受和审美做一些正常的进化算法不能做到的。

The thesis selects the American constitutional protection on private property law history from the establishment of the United States to the New Deal as study theme, and applies the theory of increasing returns path dependence and evolutionary path dependence from Oona A. Hathaway to normatively analyze this law history. Furthermore, it draws some useful conclusions on characteristics of increasing returns path dependence and evolutionary path dependence on the changing history of American constitutional protection on private property law in a Common Law System, and it also takes a few steps on applying path dependence theory on studying law history in a continental law system in our country.

论文选择美国独立战争后至新政这段时期私有财产权宪法保护法律变迁历史作为研究对象，应用哈撒维的递增报酬路径依赖和进化路径依赖理论对这段法律变迁历史进行了实证分析，总结出了美国私有财产权宪法保护法律在普通法环境下的递增报酬和进化路径依赖特性，并对路径依赖理论应用于我国成文法环境下的法律变迁研究进行了初步探索。

Nowak of Harvard's Program for Evolutionary Dynamics, Department of Mathematics, and Department of Organismic and Evolutionary Biology, examined cooperation among subjects playing a modified version of the Prisoner's Dilemma.

Nowak领导的小组对研究对象在"囚徒困境"改进版中的合作进行了研究。

K. Popper turn to ontology of three worlds, evolutionary philosophy and philosophy of biology after the middle of 60 decade last century, since he Finished his argument of his falsificationism in the fields of logic, methodology and probabilism. Popper has developed his Evolutionary Epistemology, which occupied an important place in his works during this period.

本文指出，波普尔在上世纪完成他的证伪主义的逻辑学和方法论论证及其在政治哲学中的应用的研究之后，从60年代中期开始，重点转向三个世界的本体论、进化哲学和生物学哲学的研究，其中对进化认识论研究占着一个突出的地位。

In this paper evolutionary algorithms based on probabilistic models are studied, which are new evolutionary algorithms proposed recently.

概率分析进化算法是最近几年发展起来的一类新的进化算法。

Finally, the design and implementation of vector quantizer are discussed. In the third section the theory of genetic algorithm, evolutionary strategy and evolutionary programming are discussed in detail.

第三章详细讨论了遗传算法，进化策略和进化规划这三种算法的理论，并给出了具体实现，为进化算法引入到矢量量化的码本设计中打下基础。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
