截断选择情况下的中间进化阶段
The intermediate evolution phase in case of truncated selection
摘要:
使用统计物理的方法,我们提出了严格的理论计算Eigen的准种理论与截断适应度景观,大大限制了可用的序列空间的复制准种。根据突变率,我们观察到三个阶段,一个选择性的,一个中间的一些剩余的顺序和一个完全随机化的阶段。我们的结果适用于一般情况下的适应度景观。
英文摘要:
Using methods of statistical physics, we present rigorous theoretical calculations of Eigen's quasispecies theory with the truncated fitness landscape which dramatically limits the available sequence space of a reproducing quasispecies. Depending on the mutation rates, we observe three phases, a selective one, an intermediate one with some residual order and a completely randomized phase. Our results are applicable for the general case of fitness landscape.
