Coarse graining the Cyclic Lotka-Volterra Model: SSA and local maximum likelihood estimation
C. P. Calderon, G. A. Tsekouras, A. Provata +1
When the output of an atomistic simulation (such as the Gillespie stochastic simulation algorithm, SSA) can be approximated as a diffusion process, we may be interested in the dyna…

Generalized entropy arising from a distribution of q-indices
Giorgos-Artemios Tsekouras, Constantino Tsallis
It is by now well known that the Boltzmann-Gibbs (BG) entropy can be usefully generalized into the entropy $S_q=k (1-\sum_{i=1}^Wp_i^{q}) / (q-1…

Nonextensivity of the cyclic Lattice Lotka Volterra model
G. A. Tsekouras, A. Provata, C. Tsallis
We numerically show that the Lattice Lotka-Volterra model, when realized on a square lattice support, gives rise to a {\it finite} production, per unit time, of the nonextensive en…
