An FPGA-Based Syntactic Parser for Real-Life Almost Unrestricted Context-Free Grammars
This paper presents an FPGA-based implementation of a syntactic parser that can process languages generated by almost unrestricted real-life context-free grammars (CFGs). More prec...

Polynomial Time Inference of a Subclass of Context-Free Transformations
This paper deals with a class of Prolog programs, called context-free term transformations (CFT). We present a polynomial time algorithm to identify a subclass of CFT, whose progr...

Recursive Program Schemes and Context-Free Monads
Solutions of recursive program schemes over a given signature were characterized by Bruno Courcelle as precisely the context-free (or algebraic) -trees. These are the finite and ...

A Polynomial Time Extension of Parallel Multiple Context-Free Grammar
Abstract. It is already known that parallel multiple context-free grammar (PMCFG) [1] is an instance of the equivalent formalisms simple literal movement grammar (sLMG) [2,3] and r...
