We received 68 papers as regular papers for the main conference and 14 short papers for the doctoral symposium. Each paper for the main conference was assigned four reviewers based on the preferences expressed by the Program Committee members. We ensured that every paper had at least two reviewers that expressedinterest in reviewing it or indicated that they could reviewit. We ensured that each paper got at least three reviews. As a result, only 10% of the papers were reviewed by three reviewers.The Conference Chair and the two Program Committee Co-chairs acted as Meta-Reviewers.Eachofthemtookroughly1/3ofthepapers(obviouslyrespe- ing con?icts of interest), for which s/he was responsible. This included studying the reviews, launching discussions and asking for clari?cations whenever nec- sary, as well as studying the papers whenever a need for an informed additional opinion arose or when the reviewers' notes did not allow for a decision.
