We review the problem of how to compute spectral density sparse symmetric random matrices, i.e. weighted adjacency matrices undirected graphs. Starting from Edwards-Jones formula, we illustrate milestones this line research, including pioneering work Bray and Rodgers using replicas. focus first on cavity method, showing that it quickly provides correct recursion equations both for single instan...

tein pathways) to result in a specific output (break down glycogen). Comparing a cell to a computer, as Dennis Bray does in the book Wetware: A Computer in Every Living Cell, yields a fascinating exploration into the complexity of a cell, yet shortchanges the cell and biological systems in general. The central argument of Wetware is that an individual cell contains thousands of enzymes, each pe...
