查询词典 Iterations

Furthermore, the general formula is illustrated as the weighted summation of historical position states, so as to prove that in terms of cumulative iterations, parameters of PSO have an inherent forgetting characteristic in probability, moreover the searching mechanisms of canonical PSO and Barebones particle swarm are almost the same.

通过将粒子运动的一般性描述图解为历史状态加权和的形式，进一步证明了PSO参数随迭代周期的积累，在概率意义上的遗忘特性。分析表明在经过一定周期的搜索后，标准PSO方法同Barebones粒子群方法(Barebones particle swarm， BBPS)具有近似的搜索机制。

Actively promote iterative and incremental development. Agile Modeling's practices of Model in Small Increments, Iterate to Another Artifact and Create Models in Parallel can be tough ones for experienced modelers to adopt and chances are that your experienced modelers are already chaffing at the UP's concepts of iterations, let alone an even greater emphasis on iterative and incremental modeling.

积极促进迭代增量开发敏捷建模有个实践，以小增量迭代的方式建模到另一个工件以及积极促进迭代增量开发并行创建模型，它们被有经验的建模人员坚持采用，并成为有经验的建模人员嘲讽 UP 迭代概念的机会，而并不在意那甚至是一个更加强调迭代和增量建模过程。

Many of those would require complex processing and a large number of iterations to reduce the channel estimation error.

许多人将需要复杂的处理和大量的重复，以减少信道估计误差。

This paper considers existence of extreme solutions to first-order differential equations with a parameter by the method of lower and upper solutions with monotone iterations,and monotonic sequence is uniformly converged to the extreme value solution of nonlinear equation after being constructed.

文章利用上下解方法和单调迭代技术讨论了含有一个参数的微分问题极值解的存在性，通过构造单调序列使这个单调序列一致收敛于非线性方程的极值解。

If there exists no regular quasi-attractor, the stochastic web, which is formed by the end-results of the image set of the discontinuous border and immersed in a part of the phase space, dominates the system behavior so that iterations are confined inside a part of the phase space in a"chaotic quasi-attractor"(Our research group has discovered the situation where regular and chaotic quasi-attractors coexist in a quasi-dissipative system, but this thesis will not mention it).

当类耗散系统的相空间不存在任何规则类吸引子时，这种由边界象集的归宿构成、浸入局部相空间的随机网将主宰系统，从而出现约束在局部相空间中的"混沌类吸引子"上的运动（本课题组已发现类耗散系统中规则类吸引子与混沌类吸引子共存的情况，本文未作报道）。
