== Problem Solving in Model-6 ==
See Glossary for an explanation of the interrelated terms such as: goals, actions, problems and plans.

Problems are identified in terms of a rule-based system called the '''Critic-Selector''' model, where a critic observes the problem and a selector a way for it to be solved.  In the Model-6 architecture, each layer specializes in a specific type of problem solving, so that each layer has a collection of critics that identify and propose ways to solve problems (see EM-ONE, for an implementation of the first three layers of Model-6 [http://web.media.mit.edu/~push/push-thesis.html Singh, 2005]).

* ''Reactive Critics:''  Notice problems in the internal descriptions of the world and proposes goals.
* ''Deliberative Critics:''  Classify goals and propose ways to achieve them based on past epsiodes
* ''Reflective Critics:''  Recognize problems in the deliberative layer, including planning, and suggest ways to improve the problem sovling.
* ''Self-Reflective Critics:''
* ''Self-Conscious Critics:''

=== Self-Conscious Thinking and Goals ===
Where do high-level goals come from?   High-level goals determine which problems an agent tries to solve, thus determining the subjects they "think about."  It would
