Genetic algorithms ( GA) using ordinal strings must use special crossover operators such as PMX, CX and OX, which is very bother.

But, genetic algorithms using ordinal strings must use special crossover operators such as PMX, OX and CX, instead of general crossover operators.

但是，序号编码的遗传算法不能在任意两条染色体的任意位置进行交叉，必须使用PMX，CX和OX等特殊的交叉算子，这些算子实施起来都很麻烦且效率不高。

In addition, the PMX operator as well as other genetic operators for these two problems are very efficient, and so is the responding program.

另外，本文针对指派问题和排序问题提出的PMX交叉算子以及设计的运行程序非常有效。

Besides, folate levels in embryotic tissues were also significantly reduced by PMX treatment.

，同时PMX明显降低实验组的胚胎组织叶酸水平。

In this context, America, Japan and Europe implemented the Quantitative Easing Policy ( QEP) in succession intending to stimulate demand, revive the economy and prevent a recession.

在这种经济金融大背景下，美国、日本、欧洲先后实施量化宽松的货币政策，意图刺激需求，振兴经济，防止衰退。

As a result, the interface card can generate high-precision pulse signals and can be used in detection of quadrature encoder pulse ( QEP) signal.

其主要功能是输出高精度的脉冲，对正交编码脉冲信号进行检测。
