Fackyyj loves the challenge phase in TwosigmaCrap(TC). One day, he meet a task asking him to find shortest path from vertex 1 to vertex n, in a graph with at most n vertices and m edges. (1 ≤ n ≤ 100,0 ≤ m ≤ n(n-1)) Fackyyj solved this problem at fir…

其实这个题是抄的题解啦…… 题解给了一个图,按照那个图模拟一遍大概就能理解了. 题意: 有一段程序,给你一个C值(程序中某常量),让你构造一组数据,使程序输出"doge" 那段代码大概是 SPFA的SLF优化.其实题目的意思是让我们构造一组数据,使得总的出队次数大于C.        数据范围 C<=23,333,333.输出的图中最多有100个点,没有重边.自环.负环. 思路: SLF: 设队首元素为 i, 队列中要加入节点 j, 在        时加到队首而不是队尾, 否则…

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…

Intersection between 2d conic in OpenCASCADE eryar@163.com Abstract. OpenCASCADE provides the algorithm to implement of the intersection between two 2d conic curve. The conic is defined by its implicit quadaratic equation, so the intersection problem…

Intersection between a 2d line and a conic in OpenCASCADE eryar@163.com Abstract. OpenCASCADE provides the algorithm to implementation of the analytical intersection between a 2d line and another conic curve. The conic is defined by its implicit quad…

OpenCASCADE 3 Planes Intersection eryar@163.com Abstract. OpenCASCADE provides the algorithm to search the intersection point between 3 planes. If two of the planes are parallel or identical, will get no result. Key Words. Plane Intersection 1.Introd…

Class loading in AS7 is considerably different to previous versions of JBoss AS. Class loading is based on the JBoss Modules project. Instead of the more familiar hierarchical class loading environment, AS7's class loading is based on modules that ha…

Given an array equations of strings that represent relationships between variables, each string equations[i] has length 4and takes one of two different forms: "a==b" or "a!=b".  Here, a and b are lowercase letters (not necessarily diff…

Profiling Go Programs  分析go语言项目 24 June 2011 At Scala Days 2011, Robert Hundt presented a paper titled Loop Recognition in C++/Java/Go/Scala. The paper implemented a specific loop finding algorithm, such as you might use in a flow analysis pass of a…
