Simple Dynamics for Broad Histogram Method

Paulo Murilo Castro de Oliveira

The purpose of this text is: 1) to clarify the foundations of the broad histogram method, stressing the conceptual differences between it and reweighting procedures in general; 2)…

Evolutionary Computer Simulations

Paulo Murilo Castro de Oliveira

Computer modelling for evolutionary systems consists in: 1) to store in the memory the individual features of each member of a large population; and 2) to update the whole system r…

Broad Histogram: Tests for a Simple and Efficient Microcanonical Simulator

Paulo Murilo Castro de Oliveira

The Broad Histogram Method (BHM) allows one to determine the energy degeneracy g(E), i.e. the energy spectrum of a given system, from the knowledge of the microcanonical averages <…

Why do Evolutionary Systems Stick to the Edge of Chaos

Paulo Murilo Castro de Oliveira

The long-term behaviour of dynamic systems can be classified in two different regimes, regular or chaotic, depending on the values of the control parameters, which are kept constan…

Broad Histogram: An Overview

Paulo Murilo Castro de Oliveira

The Broad Histogram is a method allowing the direct calculation of the energy degeneracy . This quantity is independent of thermodynamic concepts such as thermal equilibrium.…

Broad Histogram Relation Is Exact

Paulo Murilo Castro de Oliveira

The Broad Histogram is a method designed to calculate the energy degeneracy g(E) from microcanonical averages of certain macroscopic quantities Nup and Ndn. These particular quanti…
