std::lower_bound()将迭代器返回到元素本身 当搜索元素不存在时: 如果所有元素都大于搜索元素: lower_bound()返回一个迭代器到范围的开始。 如果所有元素都低于搜索元素: lower_bound()返回到范围末尾的迭代器(不存在下限)。 否则, lower_bound()返回一个迭代器到范围的搜索元素(比搜索元素大的最接近的元素)的...

C++ std::lower_bound() Function std::lower_bound()is an STL library function, which comes under the algorithm header library and finds the lower bound of the searching element in a range. Lower bound means the least element in the range which is greater or equal to the searching element....

因此只要证明前面的某个设定下的 upper bound,即在后面设定有相应的 upper bound;只要证明后面某个设定下的 lower bound,即在前面的设定下有相应的 lower bound。 过程 1. 定义 这篇文章假设如果有某种比较好的特征,使得 function approximation 能以最简单的线性模型表示的话,那么会有怎样的 upper bound 和 ...
