I read about LL(1), LR(0), SLR(1) and LALR(1) in many online sources and even in dragon book. However I found that no one talks about LL(0), SLR(0) and LALR(0). So I googled and come up against these two links which talk about LL(0): 1 and 2. These answers are quite satisfiable in explaining LL(0) grammars. However I still dont find anything on SLR(0) and LALR(0). Do they even exist? If yes, in what form?
