I know that LR(0)<SLR(1)<LALR(1)<CLR(1), what is the meaning of this?

However, SLR(1) parsers can parse a larger number of grammars than LR(0), and so on. Makes sense? the power represents here the ability to accept grammars. 0 votes 0 votes Vegeta commented Sep 17, 2018 reply Follow Share hello thank you for replying, we categorize the grammar like CFG, CSL, RG and all these. what does it mean LL(1), LR(0) grammar. Are we categorizing the grammar again? What is the bigger picture? You have said any grammar means it can be CFG, CSL anything? 0 votes 0 votes manisha11 commented Sep 17, 2018 reply Follow Share At syntax analyses phase we use parsers and therefore categories them as LL(0) SLR(1) and so on And for a grammar - the languages they are able to recognize. We categories as CFG CSG and so on. 0 votes 0 votes Please log in or register to add a comment.
