by Umer Zeeshan Ijaz The purpose of this tutorial is to introduce students to the frequently used tools for NGS analysis as well as giving experience in writing one-liners. Copy the required files to your current directory, change directory (cd) to t…
In the last chapter we saw how neural networks can learn their weights and biases using the gradient descent algorithm. There was, however, a gap in our explanation: we didn't discuss how to compute the gradient of the cost function. That's quite a g…
Exercises for IN1900October 14, 2019PrefaceThis document contains a number of programming exercises made for the courseIN1900. The chapter numbers and titles correspond to the chapters of the book“A primer on Scientific Programming with Python” by Ha…
这篇BLOG是我很早以前写的,因为现在搬移到CNBLOGS了,经过整理后重新发出来. 工作之前的几年一直都在搞计算机安全/病毒相关的东西(纯学习,不作恶),其中PE文件格式是必须知识.有些PE文件,比如驱动,系统会在加载时对checksum进行校验,确保驱动文件的完整性.关于PE文件如何校验,网上有很多资料可以学习,这里有一篇文章<An Analysis of the Windows PE Checksum Algorithm>是对WINDOWS API CheckSumMappedFile…
Sept. 10, 2015 Study again the back tracking algorithm using recursive solution, rat in maze, a classical problem. Made a few of mistakes through the practice, one is how to use two dimension array, another one is that "not all return path returns va…
This's my first version.The logic is simple, just the selection sort. I spent much time learning how to write AT&T assembly on 64-bit Linux.almost all books just talk about 32-bit assembly. Such as registers, on 64-bit linux, rax, rbx, rcx..... are a…
OpenCASCADE Root-Finding Algorithm eryar@163.com Abstract. A root-finding algorithm is a numerical method, or algorithm, for finding a value x such that f(x)=0, for a given function f. Such an x is called a root of the function f. In OpenCASCADE math…
Mesh Algorithm in OpenCascade eryar@163.com Abstract. Rendering a generic surface is a two steps process: first, computing the points that will form the mesh of the surface and then, send this mesh to 3D API. Use the Triangle to triangulate the param…
Manacher's algorithm 以\(O(n)\)的线性时间求一个字符串的最大回文子串. 1. 预处理 一个最棘手的问题是需要考虑最长回文子串的长度为奇数和偶数的情况.我们通过在任意两个字符之间填充 # 的方法, 将原字符串 \(S\) 转化为辅助字符串 \(T\),具体例子如下: S = a b a a b a T = # a # b # a # a # b # a # 转化后便可不必再考虑奇偶问题,同时辅助字符串的长度也变为奇数. 转化后字符串\(T\)的长度为奇数: 在长度为奇数…
I collect and make up this pseudocode from the book: <<Introduction to the Design and Analysis of Algorithms_Second Edition>> _ Anany LevitinNote that throughout the paper, we assume that inputs to algorithms fall within their specified ranges…
为学习算法和使用.实践 GIT & GitHub ,而写此系列. 我使用的编译器是 visual studio community 2015 低版本的VS打不开GitHub中的解决方案,拷贝代码是不要忘记引入 stdafx.h 中引入的文件 别外需要注意的是visual studio community 2015默认安装是不安装 MFC for c++ 的, (如下图)没有勾上这个选项的是不能新建.打开C++工程的,前两个选择是绑定在一起的,至于下面的 XP 就看各位喜好了 工程的algorit…
