Every year there is a brand new reinforcement learning competition.  This usually consists of new organizers, and a new website!

Instead of replacing the old website every year and breaking hundreds of links, we use a different subdomain each year.  So, this page will always exist at:
http://rl-competition.org
and
http://www.rl-competition.org

And the specific websites for different years are:

• NIPS Reinforcement Learning Workshop: Benchmarks and Bakeoffs
• NIPS Reinforcement Learning Workshop: Benchmarks and Bakeoffs II
• ICML Reinforcement Learning and Benchmarking Event
• NIPS Workshop : The First Annual Reinforcement Learning Competition
  
• The 2008 Reinforcement Learning Competition :: http://2008.rl-competition.org
• The 2009 Reinforcement Learning Competition :: http://2009.rl-competition.org
