Solution Concepts for Cooperative Games with Circular Communication Structure

Talman, Dolf; Suzuki, T. - Tilburg University, Center for Economic Research - 2011

We study transferable utility games with limited cooperation between the agents. The focus is on communication structures where the set of agents forms a circle, so that the possibilities of cooperation are represented by the connected sets of nodes of an undirected circular graph. Agents are...

Equivalence and axiomatization of solutions for cooperative games with circular communication structure

Selçuk, Özer; Suzuki, Takamasa; Talman, Dolf - In: Economics Letters 121 (2013) 3, pp. 428-431

We study cooperative games with transferable utility and limited cooperation possibilities. The focus is on communication structures where the set of players forms a circle, so that the possibilities of cooperation are represented by the connected sets of nodes of an undirected circular graph....

Multiperiod Hypergraph Models for Water Systems Optimization

Sechi, Giovanni; Zuddas, Paola - In: Water Resources Management 22 (2008) 3, pp. 307-320

Mathematical models describing water resources systems optimization are characterized by a large number of variables and constraints, which are needed to describe the physical components of the system, its functional ties, and its operating modalities. Some special algebraic structures allow its...
