Description

The Bron-Kerbosch Algorithm is a recursive, backtracking algorithm, widely used in fields such as social network analysis, bioinformatics, and community detection, where identifying clusters or highly interconnected subgroups is valuable. It’s efficient for finding all cliques in sparse graphs and often outperforms brute-force approaches due to its pruning techniques.
