A university registrar is scheduling final exams in classrooms to avoid conflicts; which algorithm minimizes the number of time slots needed, assuming graph coloring represents classroom availability?

💡 Explanation

The Greedy Graph Coloring algorithm sequentially assigns the 'smallest' available color (time slot) to each vertex (exam) in a graph; because this reduces time slot conflicts, the registrar can schedule exams efficiently. Therefore, the Greedy Graph Coloring algorithm minimizes the required time slots, rather than DFS/BFS for traversal or Dijkstra's for shortest paths.
