strategy

[Marsha Lovett]

the ACTION). If one takes a production rule as representing the way 
procedural knowledge is represented by the solver, then there may be many 
production-rules implementing this generic definition of strategy.

One reason for this is that in production rules, there is just as much of 
an emphasis on the conditions of applicability as on the actions.  Because 
each production rule has a condition-action pair (and because variables are 
usually bound/instantiated on the left/right hand sides), this implies that 
a prduction-rule strategy represents a relationship between the conditions 
of applicability and the actions taken.

In Lovett  & Schunn (1999; in JEP:General), we discuss how problem solvers 
might construct strategies within a production rule format. Here, the 
features in the solver's representation constrain which strategies can be 
constructed and which condition-action relationships can be made (as in "IF 
the cue color is X, then choose the option that matches X" where the action 
is defined in terms of a condition-side term).
