     In "Planning for Conjunctive Goals" (Artificial Intelligence, vol 32, 1987,
p. 333-377), David Chapman, while discussing the history of conjunctive planning
research, writes

	"The three main points of this section are that in retrospect all
	domain-independent conjunctive planners work the same way; that the
	action representation which they depend on is inadequate for real-world
	planning, and that desirable extension to this action representation
	make planning exponentially harder.  It is much longer than such
	sections are in typical AI papers because domain-independent 
	conjunction planning is unusual as a subfield of AI in showing a
	clear line of researchers duplicating and building on each other's
	work.  Science is supposed to be like that, but for the most part
	AI hasn't been."

I agree.
