Is dijkstra greedy or dynamic programming
WebJan 5, 2024 · Greedy algorithms always choose the best available option. In general, they are computationally cheaper than other families of algorithms like dynamic programming, or brute force. This is because they don't explore the solution space too much. And, for the same reason, they don't find the best solution to a lot of problems. WebWhat type of algorithm is dijkstra's algorithm? (e.g., dynamic programming, divide and conquer, greedy, etc.?) Justify your answer by explaining why Dijkstra's algorithm …

For example, sometimes it is desirable to present solutions which are less than mathematically optimal. To obtain a ranked list of less-than-optimal solutions, the optimal solution is first calculated. A single edge appearing in the optimal solution is removed from the graph, and the optimum solution to this new graph is calculated. Each edge of the original solution is suppress… lampertsgraben
