  3. This thesis suggests a process considered minimizes the population size as similar individuals occur in the fitter members of the population, which helps reduce the execution times for ga by removing the redundancy associated with the saturation effect found in the later generation. this thesis uses a method that adds dynamic penalty terms to the fitness function according to the optimal degree of solutions, so as to create a gradient toward a feasible suboptimal or even optimal solutions. on the basis of the difference of the biggest and the smallest of fitness of individual, modifying the fitness function in order to convergence is a satisfaction

    動態調節種群大小，去掉遺傳演算法在迭代後期搜索產生的過多相似個體，達到減少計算時間的目的；按照解的優劣程度給適應度函數增加一個在ga搜索過程中動態改變的可變罰函數，給搜索最優解創造一個梯度，使遺傳演算法收斂到可行的較優解或最優解；根據適應度值最大和最小個體的差修正適應度函數，使適應度函數值適中不容易造成收斂太快、局部收斂或根本不收斂而變成隨機搜索；為了避免「近親繁殖」採用競爭擇優的交叉操作；利用并行遺傳演算法的思想，提出一種自適應多子種群進化策略；提出人口汰新政策來解決類似甚至相同的個體的情況發生。
  4. With reference to calculation methods of solar radiation within domestic and abroad literature and with the help of our country ' s dem ( with its resolution is 1 km x 1 km ), we build a new model for potential solar radiation calculation combining with pci geomatica ' s platform. in the calculation, hypothesis is that insofar one clear day in more than one year as the biggest value of solar radiation of one day in many years is defined as potential value of daily global solar radiation, we also consider the infection of the slope, aspect and its geometry relations affect on solar radiation. we calculate potential solar radiation which maybe useful for research the distribution of solar energy and build large - scale grid database of our country ' s solar radiation
