Experts indicate the selection criterion of a very general form and interpret the chosen models. They can influence the result of modeling by formulating new criteria. Computer becomes an objective referee for scientific controversies, if criteria ensemble is coordinated between experts, which take part in discussion. The human element often involves errors and undesired decisions. Objective choice of optimal model by minimum of external criterion characteristic in actual GMDH algorithms often contradicts with the opinion of investigator.
Objective algorithms gives possibility to realise real artificial intelligence.
