RecursionVisualizer is an open-source Python package that creates beautiful, interactive animations of Dynamic programming (DP) algorithms. DP is one of the most difficult algorithm techniques for undergraduate computer science students to understand. Even after taking algorithms courses that focus extensively on DP, many students are still unable to correctly solve DP problems. RecursionVisualizer creates animations that address specific misunderstandings students have about DP, making it easier for both educators to teach and for students to learn about DP.
