    Maze Generators and Collective Action in Networks

    There is an intimate connection between the domain coarsening of spins in the zero-temperature Ising models and the collective behavior of opinion formation of agents in social platforms. The outcomes of these models manifest themselves in spatial patterns whose complexity in dimensions higher than one is still intriguing. Admittedly these spatial organizations are linked to Turing patterns many of which may be replicated by cellular automata (CA). In this talk, the following results will be presented: (i) When the agents demand that at least half of their neighbors be of opposite opinion, as opposed to at most half (Glauber dynamics), depending on how large the size of Moore neighboring “shells” in square lattices (the first shell includes eight agents; the second 24 neighboring contacts, and so on), the spatial patterns exhibit from maze (labyrinth) to perfect stripe patterns for periodic boundary conditions. These patterns have not been indicated in the most recent phase diagrams. Our CA simulations have verified that similar maze patterns are observed when the agents choose to place more opposite views in their second coordinating neighbors. (ii) Stubborn agents never change their opinion, while “potential nodes” may switch their decision. The information dissemination (percolation) threshold of the number of stubborn agents increases as the number of random links increases in the small-world society. However, to form a collective cluster set of the same size with a higher number of stubborn agents, more ordered motifs must be gathered.

    Dr Ali Rana Atilgan, native of Istanbul, obtained his PhD degree in the School of Aerospace Engineering at Georgia Institute of Technology. His early works focused on explanation of intriguing patterns experimentally observed for structural members made out of composite materials. His later contributions have been in the area of biomolecular systems. The elastic network models have found a wide area of applications in the biological community. Since 2006, he has been a full-time faculty member at Sabanci University, and an adjunct professor in the School of Civil Engineering at Bogazici University, both in Istanbul.
