+Blossom Algorithm (Edmonds' Algorithm) for Maximum Matching in General Graphs.
+
+The Blossom algorithm finds a maximum cardinality matching in any undirected graph.
+It was developed by Jack Edmonds in 1965 and is one of the most important algorithms
+in combinatorial optimization.
+
+This implementation provides a simplified but working version that handles
+maximum matching correctly for many practical cases.
+
+Time Complexity: O(V * E) for this simplified implementation
+Space Complexity: O(V + E)
+
+For more information, see:
