For an intriguing variety of switching processes in nature, the underlying complex system abruptly changes from one state to another in a highly discontinuous fashion. Financial market fluctuations are characterized by many abrupt switchings creating upward trends and downward trends, on time scales ranging from macroscopic trends persisting for hundreds of… (More)

The classic distributed computation is done by atoms, molecules, or spins in vast numbers, each equipped with nothing more than knowledge of their immediate neighborhood and the rules of statistical mechanics. Such agents, 10^23 or more of them, are able to form liquids and solids from gases, realize extremely complex ordered states, such as liquid… (More)

We investigate several variants of a network creation model: a group of agents builds up a network between them while trying to keep the costs of this network small. The cost function consists of two addends, namely (i) a constant amount for each edge an agent buys and (ii) the minimum number of hops it takes sending messages to other agents. Despite the… (More)
