....[b 0 ; b 0 ; b 0 z n ; a 0 ] Z) The original DCG under Prolog takes an exponential time in n to succeed, whereas our method takes a linear time. 7. COMPARISONS WITH OTHER METHODS There are several inference methods for logic programs, that use variants of LR parsing [13, 21, 28, 30, 34, 35]. In this section, we review some of these methods and compare them with SLR inference. 23 7.1. A comparison with Nilsson s AID Nilsson s alternative implementation of DCGs (AID) 21] is perhaps closest to the present work. Essentially, Nilsson first generates LR parsing tables ignoring the ....

For instance, one may cite the parallel models (independent AND parallelism[DeG84, HG90] OR parallelism[War87] the tabular models (OLDT[TS86] SLDAL[Vie87] XWAM[War89] or the magic set models[BMSU86, Sek89, UOKT84]. These models dif This work has been partially supported by the Eureka Software Factory (ESF) project. fer from the original one essentially in that they simultaneously maintain several computation branches instead of only one. This implies in particular that a variable may have multiple ....
