A simple clustering algorithm for lists
2 days ago
- The algorithm clusters list values by reversing sub-lists between identical elements, focusing on the rightmost incomplete cluster.
- It is demonstrated with an example list of b, g, o, r, showing iterative reversals to group identical values at the end.
- The algorithm is greedy and has O(n^2) time complexity, inspired by playing with Magna-Tiles.
- It resembles pancake sort but is used for clustering rather than sorting.
- The author implemented it in JavaScript with a function using nested while loops and a reverse helper.
- The author notes that humans can perform this task intuitively, but computers require explicit algorithmic steps.
