What is Median of Medians algorithm for Selection Problem?
The Median of Medians algorithm is a linear time algorithm to solve selection problem or to find median of an unsorted list. In this video, we construct and illustrate form scratch. ------------------ Time Stamps: 00:00 Intro 00:30 - Selection Problem 02:46 - First Idea (Quick Select Algorithm) 04:26 - Prune and Search Technique 05:45 - Approximate Median or Good Pivot 06:45 - Find Median of Medians and Analysis 09:40 - Runtime Analysis 12:16 - Illustration with an example 14:16 - Take Away 15:10 - Problems to Think About ------------------ IdeaBehind Series on Algorithms is a series of 15-20 (we'll count later) animated videos exploring, otherwise mysterious, algorithms in an intuitive perspective. Feedback and suggestions are welcome. ------------------ Bundle of thanks to Reed Mathis for background music. Animations done in ManimGL with Huge Thanks to Grant Sanderson.
