It maintains multi-seeds effectively, and avoids to run into trap of the part best value and precocious convergence that Simulated Niche is introduced in the selection operators.
并且在算子选择中,我们采用了模拟小生境的方法,它能够有效地维持种群的多样性,从而避免产生局部最优解,改善未成熟收敛。

很多动物学家认为，这是因为，在几乎没有任何现存竞争物种的情况下，有太多的生态小生境可供生存。
Many zoologists believe that it was because so many ecological niches were available with virtually no competition from existing species.
这个小生境行业雇佣了好几万工人，其中大多数都在家庭小作坊工作。
The niche industry employs tens of thousands of people, many of them in small, family-run workshops.
研究结果表明：喀斯特环境高度异质性，小生境小气候环境差异较大。
Then gave a series of technical measures. The result shows that: Karst environment's high heterogeneity, microhabitat and micro-climate are very different.
