Working with the LR Degrees
We say that A ≤LR B if every B-random number is A-random. Intuitively this means that if oracle A can identify some patterns on some real γ, oracle B can also find patterns on ...

Randomness, lowness and degrees
We say that A LR B if every B-random number is A-random. Intuitively this means that if oracle A can identify some patterns on some real , oracle B can also find patterns on . In o...

Faster Generalized LR Parsing
Tomita devised a method of generalized LR GLR parsing to parse ambiguous grammars e ciently. A GLR parser uses linear-time LR parsing techniques as long as possible, falling back...

IELR(1): practical LR(1) parser tables for non-LR(1) grammars with conflict resolution
There has been a recent effort in the literature to reconsider grammar-dependent software development from an engineering point of view. As part of that effort, we examine a defic...

Generalized Lr Parsing Algorithm for Boolean Grammars
The generalized LR parsing algorithm for context-free grammars is extended for the case of Boolean grammars, which are a generalization of the context-free grammars with logical c...
