On the Complexity of Possible Truth

چکیده
Chapman’s paper, "Planning for Conjunctive Goals," (Chapman, 1987) has been widely acknowledged as major step towards understanding the nature of nonlinear planning, and it has been one of the bases of later work by others (Yang and Tenenberg, 1990; Kambhampati, 1991; Ginsberg, 1990; Erol et al., 1992a; Erol et al., 1992b). But as with much pioneering work, it is not free of problems--and this has led to much confusion about the meaning of his results. Erol ~t al. (1992a; 1992b) dealt with some of these problems, and the current paper discusses another one. Chapman (1987, p. 340) states the modal truth criterion as follows:
