Abstract: We proposed a new method for generating macro operators by means of static analysis. The method selectively produces some ground actions instead of directly analyzing the description of the domain. The objects of the static analysis focus on the relations among these ground actions, which are classified accordingly. Some pattern maps are produced according to this classif ication. At last, valuable macrooperators based on the maps are generated. We also developed an experimental system to examine the method.

Key words: domain, ground actions, macro operator, pattern map
