At wisconsin ' s marquette university , a biomathematics group has existed within the math department for more than 30 years , making it one of the oldest such groups in the country 威斯康辛州马奎特大学一个生物数学研究团队在数学系里从事研究已超过三十年，是美国历史最悠久的生物数学研究团队之一。

In this paper , we modify the model , which is built by others , of human - board system of springboard diving . in the view of biomechanics and biomathematics , we build the simple model with pivot and 4 - rigid model , and make further analysis 本文是在前人已有工作的基础上，对已有的模型进行了改进，运用运动生物力学和运动生物数学分别建立了带有支点的简单模型和四刚体模型，并对模型进行了更进一步的讨论和分析。

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 本文主要验证和设计适应性操作算子和小生境方法保持群体多样性的能力，实验表明两种方法都能较好地达到目的；利用生物合作竞争模型设计协同演化来动态地改变群体规模，实验表明该模型是有效的；人工神经网络是得到越来越广泛应用的学习系统，但是由于学习算法存在一定的缺陷，如易于陷入局部极值，难以调整网络的结构等，使神经网络的应用受到一定的限制。
