2007 Braunschweig GAP 4 Packages Workshop.

GAP Package Authors Workshop took place at TU Braunschweig on September 11-15, 2007.

This informal workshop was aimed at researchers who have some experience of using GAP and are interested in developing more substantial programs or packages.

The morning sessions of the workshop were be devoted to talks contributed by the participants about algorithms, their implementation in GAP and applications. The main speakers were Graham Ellis (Galway), David Joyner (Annapolis), Max Neunhoeffer (Aachen/St. Andrews) and Csaba Schneider (Budapest). You may also view the list of participants.

The afternoon sessions of the workshop included lectures on key aspects of the design of GAP, practical sessions with advice on debugging and optimising GAP programs and discussions about future directions of GAP. Here are the links to the schedule and the abstracts.

There are pictures from the workshop here and also there.
