Editing Swarm behaviour (section)

====Altruism====
Researchers in Switzerland have developed an algorithm based on [[Hamilton's rule]] of kin selection. The algorithm shows how [[altruism in animals|altruism]] in a [[swarm]] of entities can, over time, evolve and result in more effective swarm behaviour.<ref>[http://genevalunch.com/blog/2011/05/04/altruism-helps-swarming-robots-fly-better-study-shows/ Altruism helps swarming robots fly better] {{Webarchive|url=https://web.archive.org/web/20120915092222/http://genevalunch.com/blog/2011/05/04/altruism-helps-swarming-robots-fly-better-study-shows/ |date=2012-09-15}} ''genevalunch.com'', 4 May 2011.</ref><ref>{{cite journal |last1= Waibel |first1= M |last2= Floreano |first2= D |last3= Keller |first3= L |year= 2011 |title= A quantitative test of Hamilton's rule for the evolution of altruism |journal= PLOS Biology |volume= 9 |issue= 5 |page= 1000615 |doi= 10.1371/journal.pbio.1000615 |pmid=21559320 |pmc=3086867 |doi-access= free }}</ref>
