Godfried Theodore Patrick Toussaint

Godfried Theodore Patrick Toussaint (1944 – Tokyo, 22 luglio 2019) è stato un informatico e matematico canadese, professore nella scuola di informatica dell'Università McGill a Montréal, in Canada.

Biografia

Laureatosi presso l'Università di Tulsa nel 1968, era un esperto in varie funzioni di geometria di calcolo e relative applicazioni: riconoscimento di forme, pianificazione di movimento, visualizzazione in computer grafica ed altro.

Fra i suoi interessi vi furono anche il reperimento delle informazioni musicali e la teoria musicale computazionale. È ricordato, inoltre, per uno studio scientifico sulla generazione dei ritmi musicali tradizionale tramite l'algoritmo euclideo per il massimo comun divisore (si veda ritmo di Euclide)
