The Floyd-Warshall algorithm does not assume shortest paths are limited to three edges. Instead, it uses dynamic programming to iteratively refine a distance matrix, treating every vertex as a potential intermediate node. This process naturally discovers optimal paths of any length, making Floyd-Warshall a powerful all-pairs shortest path algorithm for dense weighted graphs.
