Witryna6 kwi 2024 · Time complexity of the Prim's Algorithm is O ( (n + m) log (n)) if we use a binary heap data structure. If we use an unsorted array (assuming you meant an adjacency matrix ), then it becomes O (n^2) as you stated. Compare the time complexities: O ( (n + m)log (n)) and O (n^2) . If our graph is sparse, then n > m.
