In this article, we’re gonna talk about another type of optimization:integer programming. We’ll see why a good understanding of the problem we face is necessary to choose the right solver. Finally, we will write a model that can take on a bigger challenge and actually solve a whole clas...

在实现Python解析器(CPython)时有GIL这一概念(大部分python执行环境默认为CPython),当然,也有JPython既没有GIL。 为了利用多核,Python开始支持多线程。而解决多线程之间数据完整性和状态同步的最简单方法自然就是加锁。 也就是GIL锁。 Python的多线程在多核CPU上,只对于IO密集型计算产生正面效果;而当有至少有一个...
In this tutorial, you'll learn about implementing optimization in Python with linear programming libraries. Linear programming is one of the fundamental mathematical optimization techniques. You'll use SciPy and PuLP to solve linear programming problems.
