VeRoLog Solver Challenge 2016-2017

Dear reader,


we would like to inform you on the VeRoLog Solver Challenge 2016-2017. As of now, you can not only defend your honor but also fill your pockets: we are pleased to announce that the all-time-best instances are available from the website ( This means that you can submit solutions to any of these instances, and over time we will award small prizes for the best submissions (per instance). This prize consists of a part for the time your solution was the best one, and a part for the final best solution.


We feel that with awarding these prizes, the challenge has really kicked off. For those of you who have not registered yet, we emphasize that it is not too late! Please join us in solving this intriguing and challenging problem. Your participation will contribute to an exciting challenge and may intensify the research on this problem which is still widely overlooked in the literature.


We wish you lots of success,


Wout Dullaert, Joaquim Gromicho, Jelke van Hoorn, Caroline Jagtenberg, Gerhard Post and Daniele Vigo
