This book constitutes the thoroughly refereed post-conference
proceedings of the first two international workshops on computational
models of collaboration in distributed systems: CARE 2009, held as
satellite event of the 22nd Australasian Joint Conference on Artificial
Intelligence AI09 in Melbourne, Australia, in December 2009 and CARE
2010, held in conjunction with the International Conference on
Intelligent Agent Technology (IAT) in Toronto, Canada, in August 2010.

The 12 revised full papers presented together with 2 invited lectures
were carefully selected from a total of 45 submissions to both events.
The workshops' thematic focus is on collaborative and autonomous agents
that plan, negotiate, coordinate, and act under conditions of incomplete
information, uncertainty, and bounded rationality.
