Summary[edit]

Description
English: Evolution of altruistic cooperation in a team of clonal “Alice” robots. In the initial generation, the robots can hardly perform coordinated navigation. After 240 generations of Darwinian selection, most robots search for large food tokens and cooperate to push them towards the region of the arena under the white wall.

Media of the day This file was selected as the media of the day for 03 January 2013. It was captioned as follows:
English: These robots have had their code changed according to the principles of natural selection. After about 150 generations, this enabled them to collaborate in moving around objects larger than their size, and collecting them in a specific area of their enclosure.
