例句與造句

1. In this paper , an improved genetic algorithm ( ga ) was applied to the design of high performance e - plane waveguide filters at the first time . for dealing with the shortcoming of ga as low efficiency in local optimum searching , the idea based on parallel genetic algorithm ( pga ) known as separate local optimization was presented . by separating the whole population into sub - populations , and adding a new operator known as crossover between two sub - population , the new method can provide as 2 3 times quickly as traditional ga . all numerical examinations illustrated the high convergence speed and good global searching of the new algorithm , and proved the validity of it
   由于遺傳算法表現(xiàn)出良好的全局搜索性能，因此本文將其應(yīng)用于高性能e面波導(dǎo)濾波器的設(shè)計(jì)中.針對傳統(tǒng)遺傳算法所存在的局部搜索能力差的缺點(diǎn)，本文在并行遺傳算法的基礎(chǔ)上，通過將原有群體劃分為多個(gè)子群體，利用多個(gè)子群進(jìn)行局部極值點(diǎn)的搜索，并利用群間遷徙，使改進(jìn)后的算法收斂速度平均提高了2 3倍.數(shù)值實(shí)驗(yàn)表明算法具有較快的收斂速度和較好的全局搜索性能，證明了算法的有效性
2. It's difficult to find numerical examination in a sentence. 用numerical examination造句挺難的
