ABSTRACT

Life as evolving software

Our goal is to prove mathematically that Darwinian evolution works by studying what physicists call a toy model, one that is much simpler than the real thing, but that hopefully preserves  the essential features. DNA is digital software, so we study the evolution of randomly mutating software, a hill-climbing random walk in software space. This approach is starting to yield mathematical results, which we shall outline. For more information, see

SHORT BIO

Gregory Chaitin is the discoverer of the remarkable Omega number — which shows that God plays dice in pure mathematics — and is now trying to create a general mathematical theory of biological evolution. He worked for many years at the IBM Watson Research Center in New York. He is a member of the Academia Brasileira de Filosofia, has an honorary doctorate from the University of Córdoba  in Argentina, and is an honorary professor at the University of Buenos Aires. He has also taught  at the Instituto de Sistemas Complejos de Valparaíso in Chile, where he is Presidente Honorario  del Comité Científico, and in the Programa de História das Ciências e das Técnicas e Epistemologia  (HCTE) at the Universidade Federal do Rio de Janeiro (UFRJ). One of his books, MetaMat! Em Busca  do Ômega, was published in São Paulo by Perspectiva in 2009.
