Amplified imitation in percolation model of stock market

Makowiec, D.; Gnaciński, P.; Miklaszewski, W. - In: Physica A: Statistical Mechanics and its Applications 331 (2004) 1, pp. 269-278

The herd behavior of the Cont–Bouchaud model is amplified by allowing clusters to copy decisions of some other cluster in the next time step. The results of the model are compared to data from the Warsaw Stock Exchange. It follows that the mechanism of the amplified imitation could be...

Difference percolation on a square lattice

Vidales, A.M. - In: Physica A: Statistical Mechanics and its Applications 285 (2000) 3, pp. 259-266

Simulations of percolation processes on random site square lattices are performed implementing a different occupation … algorithm for both ordinary percolation (OP) and invasion percolation (IP) problems. The main feature of the occupation process … neighboring sites. This restriction carries an intrinsic change in the distribution of invaded sites with a different percolation …
