Decision theory is the formal study of an agent's choices [1].  

The best known decision theories are Causal Decision Theory (CDT) and Evidential Decision Theory (EDT). On LessWrong, an alternative family of decision theories has been discussed heavily with the varying names of Updateless Decision Theory (UDT), Timeless Decision Theory (TDT), and Functional Decision Theory (FDT).
