This is a blog about constraint programming, especially applications of constraint programming.
I’m Helmut Simonis, I’m a researcher at the Cork Constraint Computation Centre (4C), a research centre on Constraints, Optimisation and AI at the University College Cork. I’m also the applications editor of the Constraints journal.
Before coming to Cork, I was working in London, for the start-up companies Parc Technologies and CrossCore Optimization, while at the same time working at IC-PARC in Imperial College London as a principal research fellow. During this time I was working mainly on applying constraint programming to network management and optimization problems.
From 1990-2000 I was working as co-founder and technical director at COSYTEC in Orsay near Paris. During that time I was involved in developing many constraint applications for scheduling, personnel assignment and transportation.
From 1986-1990 I was a researcher at ECRC in Munich, a tri-national industrial research centre. At ECRC we developed the CHIP system, one of the first constraint programming platforms.
