Systems of interacting random replicators are studied using generating functional techniques. While replica analyses of such models are limited to systems with symmetric couplings, dynamical approaches as presented here allow us specifically to address cases with asymmetric interactions where there is no Lyapunov function governing the dynamics. We focus on replicator models with Gaussian couplings of general symmetry between p ≥ 2 species, and discuss how an effective description of the…

It is found that evolving random replicator systems with speciation do become large and complex, depending on speciation parameters, and the generalized Lotka-Volterra system is shown to be a tedious way of implementing the replicator system.

Model ecosystem with variable interspecies interactions

Model ecosystems with quenched, symmetric interspecies interactions have been extensively studied using the replica method of the statistical mechanics of disordered systems. Here, we consider a more

Species extinction in finite replicator systems

Species extinction in finite random replicator systems is investigated as a function of within-species interaction pressure. Extinctions are shown to increase with increased symmetry of among-species

Species extinction in finite random replicator systems is investigated as a function of within-species interaction pressure. Extinctions are shown to increase with increased symmetry of among-species

Multiple peaks of species abundance distributions induced by sparse interactions.

The replicator dynamics with "sparse" symmetric interactions which represent specialist-specialist interactions in ecological communities is investigated, and a perturbative expansion is conducted which manifests that the nature of the interactions has a direct impact on the species abundance distribution.

Statistical mechanics and stability of a model eco-system

It is shown that resources can be exploited optimally only in the absence of co-operation pressure or direct interaction between species.



Dynamics of random replicators with Hebbian interactions

A system of replicators with Hebbian random couplings is studied using dynamical methods. The self-reproducing species are here characterized by a set of binary traits, and they interact based on

We study the asymptotic behavior of effective degrees of freedom (i.e., the number of species or the diversity) of large-dimensional replicator equations (RE) with quenched antisymmetric random

Random replicators with high-order interactions

It is found that for p>2 there is a threshold value which gives a lower bound to the concentration of the surviving species, preventing the existence of rare species and, consequently, increasing the robustness of the ecosystem to external perturbations.

Extinctions in the random replicator model.

In the case of large extinction events it is found that no further biotic extinctions take place and, furthermore, that rare species become very unlikely to be found in the ecosystem at equilibrium.

Phase transition and 1/f noise in a game dynamical model.

An exact steady-state solution is presented as a function of the population's cooperation pressure u when the number of species is large and the interactions are taken as random, and when u is lowered to a critical value u c, the solution becomes unstable.

New method for studying the dynamics of disordered spin systems without finite-size effects.

It is demonstrated that there exists a critical temperature T0 which separates two different dynamical regimes depending on whether damage spreads or not in the asymptotic long-time limit, and it is suggested that damage spreading occurs due to the presence of a divergent number of saddle points in the thermodynamic limit consequence of the ruggedness of the free-energy landscape which characterizes the glassy state.
