Algorithms for finding coalitions exploiting a new reciprocity condition
2009
Logic Journal of the IGPL
Preserved Fulltext
Moreover, we provide an algorithm to search all the sub-coalitions of a given coalition satisfying the new property. ...
We introduce a reciprocity criterion for coalition formation among goal-directed agents, which we call the indecomposable do-ut-des property. ...
Algorithms for finding coalitions exploiting a new reciprocity condition 23 arises from the fact that agents prefer to form small coalitions because, as coalitions spring from unanimously agreements, the ...

As a result, humans evolved mechanisms that implement an aversion to exploitation by free riding, and a strategy of conditional cooperation, supplemented by punitive sentiment towards free riders. ...
Humans have been engaging in n-person exchanges for a great enough period of evolutionary time that we appear to have evolved a distinct constellation of species-typical mechanisms specialized to solve ...
Exchange depends on conditionally delivered behavior (e.g. I will do X if you do Y), and so necessarily requires conditional reasoning for its regulation. ...
