Parsing Algorithms Visualization Tool (PAVT) is an instructional aid that can be used to teach a course
on compiler construction. PAVT visualizes the construction of a parser for a given context-free grammar and then illustrates the use of that parser to parse a given string. PAVT can visualize six
parsing algorithms, viz. predictive parsing, simple LR parsing, canonical LR parsing, look-ahead LR
parsing, Earley parsing and CYK parsing. PAVT logically explains the process of parsing showing...
