Within this framework, we also enable consideration of surprising worlds...

Doing so clarifies decision theory and presents the opportunity to investigate alternative formulations. As an example, we take some of Savage’s notions of decision th...

We advance the position that notions of utility independence can serve similar functions when reasoning about preferences and utilities during decision making. In this paper we first summarize existing results and definitions concer...
