Greedy nearest neighbor
These are the steps of the algorithm: 1. Initialize all vertices as unvisited. 2. Select an arbitrary vertex, set it as the current vertex u. Mark u as visited. 3. Find out the shortest edge connecting the current vertex u and an unvisited vertex v. http://people.hsc.edu/faculty-staff/robbk/Math111/Lectures/Fall%202416/Lecture%2033%20-%20The%20Nearest-Neighbor%20Algorithm.pdf
