Final Update: The workshop took place on September 15 and 16, and according to the feedback we received from the participants it was successful. Thanks to all who contributed to the success of DACS 2014, and I am looking forward to the next edition. Update 2: The list of accepted papers is online. Update 1: The submission deadline for the workshop was extended to July 14, 2014, 23:59 EET. Theory Day in Computer Science 2014 (DACS-2014) is the first in a series of workshops that (hopefully) will take place yearly in Romania, focused on presenting to a mostly-Romanian audience new results on various topics related to Theoretical Computer Science. This year’s workshop takes place on the 16th of September at the Faculty of Mathematics and Computer Science, University of Bucharest, and it is affiliated to the 11th International Colloquium on Theoretical Aspects of Computing - ICTAC 2014. The main goal of the workshop series is to build a solid and modern TCS community in Romania, closely connected to the current global research-trends. Ideally, our workshop will also attract, either as invited speakers or authors of contributed papers, participants from other European countries, helping to establish international collaborations on common topics. So far, this only reflects in the composition of the Program Committee, but the submission deadline for contributed papers is still one month away: 1st of July 2014. This year we have two well-recognised Romanian researchers as invited speakers: Ion Petre - Åbo Akademi University, Turku, Finland, and Robert Mercas - Kiel University, Germany. Also, Gabriel Istrate from the West University of Timisoara has a tutorial in the first day of the workshop. Coming back to contributed papers, we look for three types of submissions: original papers, surveys, and informal presentations. While the first two types are self-explanatory, informal presentations should address work-in-progress, review some recent results, as well as present open problems. Last, but not least, we will try to keep the registration fee at a very low level, so that every interested person can come.
