We propose an efficient numerical method for two population models, based on the nonstandard finite difference （NSFD） schemes and composition methods with complex time steps. The NSFD scheme is able to give positive numerical solutions that satisfy the conservation law, which is a key property for biological population models. The accuracy is improved by using the composition methods with complex time steps. Numerical tests on the plankton nutrient model and whooping cough model are presented to show the efficiency and advantage of the proposed numerical method.

关键词： Nonstandard finite difference schemes composition methods with complextime steps population models positive numerical solutions conservation laws.

针对活动轮廓模型图像分割过程中迭代次数多,分割速度慢的问题,提出一种高阶的数值求解方法。分析活动轮廓模型中基于全局信息的CV模型,以及基于局部信息的LBF模型,LIF模型。使用二阶、三阶Runge-Kutta方法,原始Euler方法对模型进行数值求解实验对比分析。并对LBF模型中平滑项系数,时间步长的选取进行讨论。通过对非同质图像、同质图像的实验结果分析表明,所采用的数值方法能够有效地提高数值收敛精度、减少迭代次数、计算效率高。对不同系数和时间步长,数值方法也能表现出较好的稳定性。

构造加权法离散归一化梯度流,求解玻色-爱因斯坦凝聚态(Bose-Einstein condensate, BEC)的基态解,整合和扩充了离散归一化梯度流的经典有限差分法。同时,结合冯·诺伊曼(von Neumann)条件和冻结系数法证明了不同加权因子下数值格式的稳定性条件。从局部截断误差大小来看,加权法的最优加权因子为1/2。数值实验验证了加权法的稳定性条件,表明加权法可有效求解基态,且在求解过程中能量随时间演化呈递减趋势。另外,当加权因子取值为1/3时,数值结果展示对应数值格式在空间方向具有二阶收敛性。
