Object oriented development of a didactic environment used for the minimum spanning trees study

This paper presents the steps required for object oriented designing of a didactic computer system used in the study of graphical data structures, particularly for understanding the algorithms used to determine the minimum spanning tree: Prim algorithm, Kruskal algorithm, Sollin algorithm, reverse-delete algorithm and linear time randomized algorithm. The modelling of the didactic software is achieved through specific UML diagrams representing the stages of analysis, design and implementation, the software thus being described in a clear and succinct style. The interactive computer system is very useful to both students and teachers because the computer science especially computer programming is difficult to understand for most students.
