Dynamic programming is an algorithm design technique that is very difficult to learn and apply. In this paper, we introduce two extensions of the recursion visualization system SRec, intended to support dynamic programming. Firstly, SRec supports the generation of recursion forests (i.e. structured collections of recursion trees) to enhance the understanding of complex, multiple recursive algorithms...
The literature on algorithm visualizations lacks clear principles to guide the construction of effective visualizations for educational purposes. Consequently, we conducted an analysis of visualizations regarding three basic algorithm design techniques (divide and conquer, backtracking, and dynamic programming). The material analyzed was the illustrations found in prestigious algorithm textbooks,...
Algorithms are one of the core elements in computer science curricula. They involve design and analysis activities, mainly analysis of correctness and efficiency. A property which has received less attention is optimality. In order to gain insight and skills on optimization, and to promote active learning, we proposed an experimental method assisted by interactive assistants. In this paper we give...
