Neutral evolution of model proteins: diffusion in sequence space and overdispersion
Ugo Bastolla, H. Eduardo Roman, Michele Vendruscolo
We simulate the evolution of model protein sequences subject to mutations. A mutation is considered neutral if it conserves 1) the structure of the ground state, 2) its thermodynam…
Testing a New Monte Carlo Strategy for Folding Model Proteins
H. Frauenkron, U. Bastolla, E. Gerstner +2
We demonstrate that the recently proposed pruned-enriched Rosenbluth method PERM (P.~Grassberger, Phys.~Rev.~{\bf E 56} (1997) 3682) leads to very efficient algorithms for the fold…
Relaxation, closing probabilities and transition from oscillatory to chaotic attractors in asymmetric neural networks
Ugo Bastolla, Giorgio Parisi
Attractors in asymmetric neural networks with deterministic parallel dynamics were shown to present a "chaotic" regime at symmetry eta < 0.5, where the average length of the cycles…
