S.N. LR(0) LR(1) -------------------- 1 Item has no look-ahead: form $[A \to \alpha.\beta]$ Item carries a look-ahead: form $[A \to \alpha.\beta, a]$ 2 Reductions applied on all input symbols (LR(0)/SLR use FOLLOW) Reduction applied only on the item's specific look-ahead 3 Less powerful; more shi...
