A-Graph software that may be used for the teaching - learning of the Graph Theory and its Algorithms discipline. The A- Graph is basically an editing program for directed and non directed graphs. There are two main features on this software: display of the incidence and adjacency matrices and the execution of the DFS and BFS search algorithms. You can also export the graph in jpg format and svg format, and allows saving the geometry and topology of the graph in an ASCII text file.
