I am facing the problem of identifying the LR-ness of the grammar.
Suppose, there is a grammar and one new rule is added in the grammar.


My question is if there exists a algorithm for identifying whether the
modified grammar is LR or non LR without re-generating the full LR
state machine.


Thanks
Alpana
