A* runs fastest with the fewest graph nodes; grids are often easier to work with but result in lots of nodes. This page covers the A* algorithm but not graph design; see my other page for more about graphs. For the explanations on the rest of the page, I’m going to use grids ...
This book emphasizes the creative aspects of algorithm design by examining steps used in the process of algorithms development. The heart of this creative process lies in an analogy between proving mathematical theorems by induction and designing combinatorial algorithms. The book contains hundreds of pr...
4.2 Strassen‘s algorithm,很美妙的算法,令人震惊 4.3 substitution method,可能面试的时候不会用到,但是这是最基础的工具去寻找递归算法的时间复杂度 4.4递归树分析,和4.3一样重要 4.5master method,重要到最好可以深刻到潜意识里,面试中需要即时使用在算法的时间度分析中 4.6 proof of the master theorem,可以跳过...
