使优化

A tail thus enables the bird to have wings that are optimized for cruising speed (with the tail furled to minimize drag) and, at low speeds, the spread tail reduces induced drag during manoeuvring and turning flight.

一条尾巴，从而使鸟类有翅膀是优化的巡航速度（与尾巴furled ，以减少阻力），并在低速，传播尾巴减少诱导阻力在操纵，把飞行。

They were designed to optimize prototyping and minimize production costs.

它们的目的是优化产品原型，以及使生产成本降到最低。

Under the given project scheduling specified by the upper-level algorithm, combined with a critical chain-based heuristic, the lower-level genetic algorithm reallocates the resources to shorten the project duration so that the rate of converging to the global optimum district is improved, and a variable mutation probability is developed to avoid premature convergence.

在由上层算法确定的调度顺序下，下层遗传算法结合基于关键链的启发式算法，对系统资源重新优化配置，使算法加速向最优解区域收敛，并在下层设计了随迭代代数增加的可变变异概率，以避免早熟收敛。

In this thesis, the author brings out the feasibility of studying using the genetic algorithms in the selection of AGC units.

通过对AGC机组调配优化算法的改进，从而实现AGC服务的最优原则，即在满足系统要求的条件下，使电网的资金消耗最小。

One technique is conventional in focus CBED, in which the residual strains were determined by using optimization algorithms to fit the calculated higher order Laue zone line patterns with experimental ones.

常规正焦CBED方法中，用优化算法使计算的高阶Laue带线图与实验图达到最佳拟合，进而确定残余应变。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
