In the 1980s Siemion Fajtlowicz, at the University of Houston, wrote Grafitti, the first program to make mathematical conjectures. A fair number involved the independence number. For many years Fajjtlowicz maintained a list of conjectures, Written on the Wall, as well as comments about the conjectures and updates on their status. These were posted on my webpage when I was at UH, but have since been unavailable. Maybe some of Graffiti’s independence number conjectures will inspire new work?
