In the last century, Claude Shannon demonstrated that adding more data is needed to decrease uncertainty in data transmissions, prompting the creation of another source of data.

To develop these algorithms the 60 researchers involved used techniques that include game theory (in which agents have to overcome barriers to collaboration in order to get the best outcome), probabilistic modelling (which is employed to predict missing data and reduce uncertainty) and optimisation techniques (which can provide means of making decisions when communications between agents are limited).
