During the reproduction process the offspring's code is occasionally
changed – mutated. In Avida one can control both the kinds and rates
- Point mutations: an instruction is changed to another
instruction by a “cosmic ray”.
- Copy mutations: Occasionally an instruction is mis-copied
- Indels – Insertion and deletion mutations.
Indels increase or decrease genome length.
- Divide mutations: Mutations that occur when the offspring
is being separated from its parent.
Mutation types and probabilities are specified in the
GENESIS file. See the program documentation on your memory stick.
