The "Nordic Network for researchers and practitioners of Constraint programming" (#NordConsNet) will be held June 8-9 in Odense, Denmark. Participation is free (registration is required).

And - unrelated to these CP conferences - I'm now preparing a 1h30min talk "Constraint Programming - Solving Combinatorial puzzles when you are lazy" (in May 19). Mostly on Constraint Modeling using #MiniZinc (and some #Picat).
