Specifically, I want to know what kind of control language is available using the shell. For example, can the programmer specify how a task would be broken into sub-tasks and for each sub-task, can the programmer specify a particular inference routine (specifically, forward-chaining, backward-chaining, depth-first search, breadth-first search, best-first-search, or any other inference routines)? Any information would be welcome. Thank you in advance. wang@ai.utoronto.ca
