However, given an infinite source of energy, population growth still produces an inescapable problem. 但是,即使有无穷能源,人口增长依然带来不可逃避的问题。
The neutral theory claims that the overwhelming majority of evolutionary changes at the molecular level are caused by random fixation ( due to random sampling drift infinite population) of selectively neutral ( i.e., selectively equivalent) mutants under continued inputs of mutations. 中性论认为在分子水平上覆盖着多数的进化改变,是在连续产生突变时,由于选择中性(即选择相等),使突变得到随机的固定(即小群体内,样本的随机漂变)。
This paper quantitatively analyzes the infinite population dynamics system of the gene pool GA and discusses the influence of the solution space scale on the stability of the gene pool GA. 对基于基因池重组遗传算法的无限种群动力系统进行了分析,讨论了参数搜索空间规模对系统稳定性的影响。
Existence of Positive Almost Periodic Solution for a Class of Population Differential Equation with Infinite Delay Population Dynamics of Two-Sex Models 一类种群动力学模型正概周期解的存在性
Two complex evolution systems are analyzed based on infinite population model of the genetic algorithm. According to the analytical results, two new evolution systems are constructed, and the iterative equations of the dynamical system models of both evolution systems is derived in one-bit case. 分析了两类基于遗传算法无限种群模型的复杂进化系统,在此基础上构造了两类新的种群进化系统,并推导出了它们在单基因位情况下的动力方程。
In the infinite population evolution equation in the population system is presented the local asymptotic stability condition. 在无限时滞种群发展方程里给出了种群系统的局部渐进稳定的条件。
