Proceedings of the Twenty-Third International Joint Conference on Artificial Intelligence

The International Joint Conference on Artificial Intelligence (IJCAI) is the premier international gathering of leading AI researchers and practitioners from all over the world. Held biennially in odd-numbered years since 1969, IJCAI highlights the latest theoretical and applied results in all subfields of artificial intelligence. The theme of IJCAI-13 was AI and computational sustainability. For this reason, besides the main track, the conference had a special track on this topic, with both technical papers and data challenge papers. All the papers accepted in this track (23 technical papers and 3 data challenge papers) are included in the 413 accepted papers and appear in these proceedings.
