The Thirteenth Scandinavian Conference on Artificial Intelligence is held in Halmstad, Sweden, on the 4^th and 5^th of November 2015. The conference is organised by Halmstad University together with SAIS, the Swedish Artificial Intelligence Society. SCAI is the main biennial conference for the AI research communities of Scandinavia. The first SCAI conference was held in 1988 in Tromsø, Norway. Although its primary function is to assemble researchers from the Nordic countries, it has constantly attracted a rather international participation.

This year's program consists of a Doctoral Symposium, two workshops (Intelligent and Connected Vehicles and Intelligent Environments Supporting Health and Wellbeing) and the main conference, with seventeen regular paper presentations and two invited speakers (Christine Chevallereau and Christopher Nugent), as well as the annual meeting of the Swedish AI Society (SAIS). The contributions submitted for presentation at SCAI 2015 cover a wide range of topics, including machine learning, data mining, logical reasoning, robotics, planning, and more. Both papers focusing on the theory, as well as those presenting applications of AI, are well represented in the selection.

This year we feature the second edition of SCAI Doctoral Symposium, where PhD students have an opportunity to present their research-in-progress to a panel of experts. Extended abstracts of these presentations are included in these proceedings.

The conference organisers and editors of this volume would like to thank all the authors who submitted their papers to the conference, as well as the members of the program committee for their work in evaluating those submissions. The PC members ensured that each contribution was reviewed by at least two, and in most cases by at least three, competent referees.
