查询词典 iterations

The numerical ex-periment has shown that the number of iterations depends significantly on the positiveparameterα,β. But, in general, it is di?cult to choose a proper parameterα,β. Thuswe propose new self-adaptive alternating direction method which adjusts the scale pa-rameter automatically per iteration based on the message of the iterates. We have provedthe convergence of the method under mild assumptions.Finally, we present some numerical results.

对于我们提出的新交替方向法，数值实验表明，迭代的步数与时间与所取的参数α，β有关，然而我们很难去选择一个合适的参数α，β，因此我们提出新自适应交替方向法，对其中的参数α，β进行自适应调整，这种自适应算法根据每步迭代信息自动地调整参数α，β，并证明了算法的收敛性。

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.
