Macro Operators

Aliases: MACROPS, Triangle Table

Keywords: learning, preconditions

Categories: Learning , Planning

Author(s): Maarten van Someren

It is possible to combine a sequence of Operators to build a new one, a macro operator, that has the effect of the sequence. Its list of preconditions contains all preconditions of the first operator of the sequence, plus those of later operators in so far as they have not been satisfied by previous operators in the sequence. The ADD and DELETE LISTS are determined in the same way. Macro operators can be represented like `basic' operators and be added to the set of existing operators. This is a form of learning that will reduce search in new problems.
