列生成算法(Column Generation Algorithm)是一种用于求解大规模线性优化问题的高效算法,其理论基础由Danzig等人于1960年提出。本质上来讲,列生成算法是单纯形法的一种形式,用来求解线性规划问题。 一、 产生背景 在某些线性规划问题的模型中,约束条件的数目有限,但变量的数目会随着问题规模的增长爆炸式的增长,很难把所...

pandas.reset_index in Python is used to reset the current index of a dataframe to default indexing (0 to number of rows minus 1) or to reset multi level index. By doing so the original index gets converted to a column.
