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 ...
TheAdam optimization algorithmis an extension to stochastic gradient descent that has recently seen broader adoption for deep learning applications in computer vision and natural language processing. In this post, you will get a gentle introduction to the Adam optimization algorithm for use in deep lea...

algorithm design as well as the mathematical aspects. In its new edition, Introduction to Algorithms continues to provide a comprehensive introduction to the modern study of algorithms. The revision has been updated to reflect changes in the years since the book's original publication. New chapters...
Cormen 等著 The MIT Press,Introduction To Algorithms算法导论,2,Chapter 1. Introduction,3,1.1 算法(Algorithm),非形式定义:一个算法是任何一个良定义(well-defined)的计算过程,它接收某个值或值的集合作为输入,产生某个值或值的集合作为输出。因此,一个算法是一个计算步骤的序列,这些步骤将输入转化为输出。
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...

An algorithm is an effective method that can be expressed within a finite amount of space and time and in a well-defined formal language for calculating a function. Starting from an initial state and initial input (perhaps empty), the instructions describe a computation that, when executed, pro...
