Avida: A Software Platform for Research in Computational Evolutionary Biology

Abstract: Avida is a software platform for experiments with self-replicating and evolving computer programs. It provides detailed control over experimental settings and protocols, a large array of measurement tools, and sophisticated methods to analyze and post-process experimental data. We explain the general principles on which Avida is built, as well as its main components and their interactions. We also explain how experiments are set up, carried out, and analyzed.

“…Our model organisms are digital creatures evolved within the Avida system (Ofria and Wilke, 2004). This has several advantages: (1) we can readily simulate many organisms in very different conditions and (2) for each artificial organism (or 'avidian') we have a clear correspondence between its genome (instructions) and the different logic tasks solved by the organism (its phenotype).…”

“…Avida is an ABM in which selfreplicating "digital organisms" compete for resources in the form of CPU memory (Ofria and Wilke 2004). Ofria and colleagues discuss a case in which they wanted to study a population that could not adapt, but would accumulate deleterious or neutral mutations through genetic drift.…”

“…The main purpose of the system was to understand the process of evolution, rather than solve computational problems. Avida, in turn, was an extension of Tierra that guided evolution to solve simple problems [82]. Avida has been largely used to simulate biological and chemical systems [1], but was also extended to other interesting problems that need robust and adaptive solutions.…”
