AVIDA is NOT a Genetic Algorithm- Tierra is NOT a Genetic Algorithm
Some evos understand that neitehr AVIDA nor Tierra are genetic algorithms. However evoTARDs think that one or both are.
Wikipedia explains what they are:
Avida is an artificial life software platform to study the evolutionary biology of self-replicating and evolving computer programs (digital organisms).
Tierra simulated an evolutionary system by introducing computer programs that competed for computer resources, specifically processor (CPU) time and access to main memory.Genetic algorithms are for solving problems. They should be finite, ie have an end. They employ goal-oriented targeted searches to solve their respective problems. Neither Avida nor Tierra have goals. They may employ algorithms but they are not algorithms. Computer simulations, yes. Genetic algorithms, no.
