WebNov 20, 2024 · First we present a fast greedy approximation algorithm that builds k centers using a farthest-first traversal in k iterations. This algorithm improves the previous approximation factor of the unrestricted assigned k-center problem from 10 (see [1]) to 6. Next we restrict the centers to be selected from all the probabilistic locations of the ...

WebA farthest-first traversal is a sequence of points in a compact metric space, with each point appearing at most once. If the space is finite, each point appears exactly once, and the traversal is a permutation of all of the points in the space. The first point of the sequence may be any point in the space. Each point p after the first must have ... Webb) Treat the farthest node from the root as the start node. c) Traverse from the start node and reach the farthest node using Depth First Search (DFS). The farthest node is the end node of the longest path. Note: To print the actual path from the start node till the end node, we can do another DFS traversal.
