摘要:

本文的目的是应用两种类型的粒子群优化算法,全局最优和局部最优粒子群优化算法来解决生物信息学中的伪时间分析中的约束极大似然估计问题。结果表明,当优化问题是不可微的、非凸的,无法得到解析解,不能应用基于梯度的方法时,粒子群算法是非常有用和有效的.

英文摘要:

The aim of paper is to apply two types of particle swarm optimization, global best andlocal best PSO to a constrained maximum likelihood estimation problem in pseudotime anal-ysis, a sub-field in bioinformatics. The results have shown that particle swarm optimizationis extremely useful and efficient when the optimization problem is non-differentiable and non-convex so that analytical solution can not be derived and gradient-based methods can not beapplied.
