The Epsilon State Count
Bram Bakker, Michiel de Jong · The MIT Press eBooks · 2000
Terminology and de#nitions are proposed for the application of systems concepts to Adaptive Behavior research. The de#nition of a system can be applied to agents and environments in several ambiguous ways. For this reason, a distinction is introduced between a mechanistic perspective and a functional perspective. For both perspectives a methodology is proposed for estimating the number of states of an agent, yielding the Mechanistic Epsilon State Count and the Functional Epsilon State Count, respectively. In addition, a similar means is proposed for counting the number of states required to perform a particular task in an environment: the Task Epsilon State Count. Importantly, the methodology explicitly looks for and reports the relation between the number of states and their e#ect on performance. This methodology provides a uniform language to describe and compare di#erent agents and environments, and for this reason it may a#ord valuable comparisons between di#ere...
