Thirdly, resorting to cooperation - competition model of biomathematics, this thesis proposes a new co - evolution model. simulation results are shown to verify its effect and practicabilitv. last, standard methods for optimizing neural netvvorks are easily trapped into local optimization, and unable to adjust the structure of neural networks, thus their application is limited to certain extent
本文主要驗證和設計適應性操作運算元和小生境方法保持
群體多樣性的能力,實驗表明兩種方法都能較好地達到目的;利用生物合作競爭模型設計協同演化來動態地改變
群體規模,實驗表明該模型是有效的;人工神經網路是得到越來越廣泛應用的學習系統,但是由於學習演算法存在一定的缺陷,如易於陷入局部極
值,難以調整網路的結構等,使神經網路的應用受到一定的限制。

The complete nucleotide sequence of the mitochondrial genome of f. limnocharis was detailedly compared with those of 5 other amphibians. the nucleotide sequences of 22 trna encoded by 6 amphibians mitochondrial genomes were combined and aligned to the homologous sequences of the 11 veterbrate taxa. using teleosts as outgroup, the phylogenetic analyses results show that mp, nj and ml trees all strongly support the monophyly of living amphibians with respect to other living tetrapods and favor a sister group relationship for caecilians and salamanders
