The algorithm defined the mutation probability according to distance density and fitness,adopted improved crossover and simulated annealing operation.
为了提高基于距离测度的自适应遗传退火算法的收敛概率和收敛速度,提出了一种改进的算法,定义基于距离密集度和适应度的自适应变异概率,采用改进的算术交叉操作和模拟退火操作,并在群体趋于一致时保留最优个体,重新产生其他新个体。

The recommendation to amend the Law of Land Administration should be:add some items about density of population, different density, different management;take the value of land in market into account, expand the range of compensation for land expropriation; change and define the meaning of the collective ownership.
本文从当前农村土地管理的现状和问题着手,分析现行《土地管理法》存在的缺陷,并在考察国内部分地区先行先试和越南、印度等国经验比较的基础上,提出修改《土地管理法》的建议:把人口密度这一因素纳入法律考量范围,按人口密度实行土地分类管理;把土地自体价值纳入征收补偿范围;对“集体所有”进行词性和语义再造。
This article demonstrates it from the relationship of the density of population and mode of production,namely,mode of economy,which is generally ignored by our colleague scholars.
从被同人学者所忽略的人口密度与生产方式即经济形态的关系来论证,中国从战国以来就已经是一个人口密集的国家;正是这种人口密度大的状况,导致了中国封建社会没有走西欧封建社会那种领主制下的大庄园经济的道路,而是走了中国独特的地主制下的小农户经济的道路。
