Asynchronous Coordination Under Preferences and Constraints
[chapter]
2016
Lecture Notes in Computer Science
Preserved Fulltext
The main message of this paper is that finding optimal solutions to the coordination with constraints and preferences task requires to design "dynamic" algorithms, that is, algorithms of a completely different ...
Otherwise, the agents must coordinate to resolve their conflicts, and potentially choose non preferred resources. ...
Coordination with constraints and preferences in K x,y is unsolvable for more than one process.
Proof. ...
