我们考虑了一个具有随机突变和选择的无性繁殖个体模型。突变率与种群大小成正比。突变可能是有益的，也可能是有害的。Yu， Etheridge和Cuthbertson（2009）的论文推测该模型中平均适应度增加的平均速率为$O(log N/(log N)^2)$。在本文中，我们证明了对于任意时间$t > $存在值$epsilon_N right - row 0$和一个固定的$c bbb_1 0$，使得在[epsilon_N，t]$中的所有时间$s，总体的最大适应度大于$ cslogn /(loglogn)^2$，并且当$N$趋于无穷时，概率趋于1。
We consider a model of asexually reproducing individuals with random mutations and selection. The rate of mutations is proportional to the population size, $N$. The mutations may be either beneficial or deleterious. In a paper by Yu, Etheridge and Cuthbertson (2009) it was conjectured that the average rate at which the mean fitness increases in this model is $O(log N/(loglog N)^2)$. In this paper we show that for any time $t > 0$ there exist values $epsilon_N
ightarrow 0$ and a fixed $c > 0$ such that the maximum fitness of the population is greater than $cslog N/(loglog N)^2$ for all times $s in [epsilon_N,t]$ with probability tending to 1 as $N$ tends to infinity.
