6 votes 6 votes $LR(0)\subset SLR(1)\subset LALR(1) \subset CLR(1)$ If there is no RR conflict in CLR(1) then there may or may not be RR conflict in LALR(1) If there is no SR conflict in CLR(1) then there is no SR conflicts in LALR(1) Number of states in SLR(1) and LALR(1) are same, goto moves are identical ,shift moves are identical, reduce moves may different else point 1 will never be satisfied. LALR(1) and CLR(1) both uses LR(1) items. LR(0) and SLR(1) both uses LR(0) items. erh answered Dec 28, 2017 erh comment Share Follow See all 3 Comments See all 3 3 Comments reply Warlock lord commented Dec 30, 2017 reply Follow Share yes, LALR and SLR may have different reduce moves, so to satisfy point 1, number of reduce moves in LALR must be lesser or equal to SLR, am I right? 0 votes 0 votes erh commented Jan 2, 2018 reply Follow Share @Warlock lord yes 0 votes 0 votes Rupendra Choudhary commented Jan 19, 2018 reply Follow Share Hello erh Don't mind but I doubt if your are really answering the question or just sharing what you know. If would be of much help if you clear your each and every point with examples rather than just putting statement in form of results. 0 votes 0 votes Please log in or register to add a comment.
