说明：  一楼房的后面是一个很大的花园. 在花园中紧靠着楼房有一个温室,温室伸入花园2m,高3m,温室正上方是楼房的窗台. 清洁工打扫窗台周围,他得用梯子越过温室,一头放在花园中,一头靠在楼房的墙上. 因为温室是不能承受梯子压力的,所以梯子太短是不行的. 现清洁工只有一架7m长的梯子, 你认为它能达到要求吗? 能满足要求的梯子的最小长度为多少?(The back of a building is a big garden. In the garden close to a building in a greenhouse, greenhouse into the garden 2m, high-3m, the greenhouse is the top of the building' s bay windows. Cleaners cleaning around the windowsill, he crossed to use a ladder greenhouse, on a garden, against a building wall. because of the greenhouse can not bear the pressure of a ladder, so the ladder is not too short. cleaners are only a 7m long ladder, do you think it can meet the requirement it? ladder to meet the requirements of the minimum length of the number?)

说明：  （插值） 在某海域测得一些点(x,y)处的水深z由下表给出，船的吃水深度为5英尺，在矩形区域（75，200）*（-50，150）里的哪些地方船要避免进入。 ((Interpolation) measured the waters in a number of points (x, y) the Agency' s water depth z is given by the following table, the ship' s five feet depth of water in the rectangular area (75,200)* (-50,150) in where the ship to avoid.)

类聚的概念 对一些有需要的 人还是比较有帮助的 (buzhidao )

基于Matlab的遗传算法~是模拟达尔文生物进化论的自然选择和遗传学机理的生物进化过程的计算模型，是一种通过模拟自然进化过程搜索最优解的方法，它最初由美国Michigan大学J.Holland教授于1975年首先提出来的，并出版了颇有影响的专著《Adaptation in Natural and Artificial Systems》，GA这个名称才逐渐为人所知，J.Holland教授所提出的GA通常为简单遗传算法（SGA）。(SGA 《Adaptation in Natural and Artificial Systems》)
