A graph \(G(V, E)\) is called bipartite if its vertices can be divided into two groups \(X\) and \(Y\) such that every edge connects one vertex from \(X\) and one vertex from \(Y\). The graph drawn below is bipartite.
Given a graph, can you determine if it is bipartite? Continue reading An Online Algorithm to Check for Bipartite Graphs
Let’s think about the following problem:
Consider a wall that stretches to infinitely in both directions. There is a robot at position \(0\) and a door at position \(p\in\mathbb Z\) along the wall \((p\neq 0)\). The robot would like to get to the door, but it knows neither \(p\), nor the direction to the door. Furthermore, the robot cannot sense or see the door unless it stands right next to it. Give a deterministic algorithm that minimizes the number of steps the robot needs to take to get to the door.
This problem quite famous Continue reading A Blind Robot Beside an Infinite Wall
