Opportunism without Deliberation
Louise Pryor · 1996
Introduction Recently, increasing attention has been given to the problem of how to produce goal-directed behaviour in the real world. The approaches taken vary along a spectrum from trying to extend the scope of classical planning techniques in systems such as Cassandra (Pryor & Collins 1996) and buridan (Kushmerick, Hanks, & Weld 1995); via including execution in plan construction systems such as Sage (Knoblock 1995); through developing systems such as raps that execute ready-made plans (Firby 1989; 1996); to the design of systems that compile plans into sets of reaction rules (Schoppers 1987; Schoppers & Shu 1996). It seems reasonable to suppose that eventually much of this work will converge somewhere near the centre and will result in systems that seamlessly integrate plan construction with plan execution, thus allowing planning, re-planning and acting to be interleaved. Indeed, this is the theme of much recent research as evidenced by many
