线性规划改进单纯形法的一个注记
Based on the gaussian elimination technique and its relevant theory of the matrix decomposition , a variant of the revised simplex method that possesses better numerical stability is discussed
摘要根据高斯消去法及其相关的矩阵分解理论，讨论了具有较好数据稳定性的改进单纯形法的一种形式。
The method of modified simplex was applied to optimize the models , and the fitting results show that liu - logistic model was more suitable than logistic model to the actual growth trend of form . taxus chinensis var . mairei population , and the highest growth rate of basal area was the tenth age class , namely the phase when breast diameter was 68 ~ 76 cm
以胸高断面积代替种群生物量，分别采用logistic常规模型及刘金福提出的logistic改进模型对南方红豆杉种群的增长动态进行研究，运用改进单纯形法对模型进行优化，拟合结果表明改进模型比logistic常规模型更符合南方红豆杉种群的增长趋势，南方红豆杉种群的最大增长速度出现在第10龄级，即胸径为68 76cm时期。
