The range of evolutionary theories during "the eclipse of Darwinism" included forms of "saltationism" in which new species were thought to arise through "jumps" rather than gradual adaptation, forms of orthogenesis claiming that species had an inherent tendency to change in a particular direction, and forms of neo-Lamarckism in which inheritance of acquired characteristics led to progress.

在"达尔文主义衰落时期"，进化理论包括各种形式的"骤变说"，认为新种是通过"跳跃"而不是通过逐渐适应产生的；也包括各种形式的直生论，声称物种有着内在的、向某一特定方向变化的趋势；还包括各种形式的新拉马克主义，认为获得性状遗传导致进步。

A fine-grained genetic algorithm based algorithm which is for the parameters optimization problem of agent model is proposed. The fine-grained genetic algorithm is used to solve the parameters optimization problem of agent model. As to the parameters optimization problem of the agents colony model, the first step is to define the concept of "the parameters mode of the combat agents colony" to describe the parameters of the combat agent colony model. Then the genetic algorithm is used to solve the optimization problem with the parameters mode of the combat agent colony model as the genetic individual. Besides the algorithm, the algorithm dispatch tactic is also considered. And the two level sequence dispatch tactic and the two level nesting dispatch tactic are put forward for those complex parameters optimization problem. At last, the model parameters optimization under antagonism codition is studied. The means to solve this problem is to translate it into a kind of antagonism problem, then use the competitive co-evolutionary genetic algorithms to solve it.

In this implementation, the evolutionary algorithm is hybridized with the simulated annealing algorithm and the hill climbing heuristic. The main aspects are as follows. The Metropolis criterion of the simulated annealing algorithm is introduced to select the offspring in order to make the algorithm more effective to escape the local optimum. In terms of the hill climbing heuristic, the local normal perturbing mutation operator based probability selecting is developed to enhance the local searching of the algorithm.

其主要工作是将进化算法与模拟退火算法及爬山方法相组合，引入模拟退火算法中Metropolis接受准则选择子代，提高算法跳出局部最优解的能力：借鉴爬山方法思想，构造了基于概率选择的局部正态摄动变异算子，以强化进化算法局部细搜索能力；同时进化算法以多种群方式实现，在降低计算时间的同时提高算法收敛到全局最优解的概率。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
