About ModRef

ModRef grew out of a run of workshops and sessions on modelling and reformulating constraint problems — a modelling session at CP 2001, and earlier meetings at CP, ECAI and IJCAI. The first standalone workshop was held in 2002, alongside CP at Cornell.

Its name has widened with its scope: from Reformulating Constraint Satisfaction Problems in 2002, to Modelling and Reformulating Constraint Satisfaction Problems in the years that followed, and finally to today's Constraint Modelling and Reformulation. Across twenty-five editions it has followed the CP conference around the world — Ithaca, Kinsale, Sydney, Perugia, Melbourne, Lisbon and beyond — and remains a small, focused venue for new ideas on how we model and reformulate.

About this archive

This site collects the history of the series with a searchable list of every contribution and its papers and slides. It supersedes the series page formerly maintained at www-users.york.ac.uk/~af9/ModRef, which is no longer updated. Recent editions each keep their own site at YEAR.modref.org; some older links point to Internet Archive captures.
