Enabling-Condition Interactions and Finding Good Plans

In AI planning research, the best-known goal interaction is the deleted-condition interaction, in which the side-effect of achieving one condition is to delete some other condition that will be needed later. Enabling-condition interactions---in which the side-effect of achieving one condition is to make it easier to achieve some other condition---are not as well known. In this paper, I argue that enabling-condition interactions merit more attention than they have heretofore received.
