Let’s use queue brilliantly!Breadth First Search with C++!
BFS (Breadth-First Search) is one of the popular ways to search all of the vertices on a given graph. I write this article to understand well.
Expected value of the number of trials until it occurs with probability p
An expected value of the number of trials with probability p is calculated. It's not so hard to see why but for my understanding I tried to calculate it.
How to remember a rotation matrix
This time I introduced the simple way to remember the rotation matrix. Where is the minus sign? Which comes first, sin or cos? You can easily calculate the matrix if you read this.
Floyd-Warshall algorithm
This time I introduce Floyd-Warshall algorithm that finds the minimum distance between all vertex pairs with O(V^3) complexity. Read this!
