Predicting and generating time series by neural networks: An investigation using statistical physics
Every time one has some ob jects or agents in mutual interaction, one can consider these objects or agents as the nodes (vertices) of a graph and represent pictorially the existence of the interaction by an abstract link (edge) connecting two nodes.

The agents do not adapt, and the success of the system is determined by the starting locations of the agents.

Stochastic Maps, Wealth Distribution in Random Asset Exchange Models and the Marginal Utility of Relative Wealth
Whether agent i or j will ‘win’ in a particular trading encounter is decided by the toss of a fair coin, i.e., each has a probability 1/2 of making a net gain. A possible variant, where, the two agents randomly redistribute their total wealth can be seen as a manifestation of the TF model.

For example, instead of allowing all the agents to trade among themselves, we can forbid trade between agents B and C (say).
