What is Cabri?

A tool for Research and Teaching in Graph Theory

This software will allow you to handle graphs as you would do it on paper, with all the facilities and power a microcomputer can bring. The main interest of CABRI ("Cahier de brouillon informatique", i.e. "computerized notebook") lies in its highly interactive character. The objects manipulated by CABRI are sets of points together with edges interconnecting them. The incidence relation between points (also called vertices) and edges is the only mathematical structure involved, and geometrical aspects are ignored.
Up to now, CABRI only considers graphs without loops or multiple edges - such graphs are called "simple".

CABRI consists essentially of a graph editor, associated with a toolkit allowing different computations, such as the evaluation of graph invariants or the performing of some classical transformations.
Finally, a random generator of graphs, satisfying a number of parametrizable properties, has been specially developped to allow the user (student, teacher or researcher in Graph Theory) to experiment with theorems. Thus, one may also invalidate a hasty conjecture, or on the contrary, bring some support to a more elaborate one.

Compatibility notes

Doesn't play well with MultiFinder, you have to bring it to the foreground in the MultiFinder menu after the splash screen

Emulating this? It could probably run under: Mini vMac
