JFLAP Version 7.1 RELEASED July 27, 2018

JFLAP

JFLAP is software for experimenting with formal languages topics including nondeterministic finite automata, nondeterministic pushdown automata, multi-tape Turing machines, several types of grammars, parsing, and L-systems. In addition to constructing and testing examples for these, JFLAP allows one to experiment with construction proofs from one form to another, such as converting an NFA to a DFA to a minimal state DFA to a regular expression or regular grammar.

• Aug 25, 2018 - JFLAP Videos page added.
  
  
• July 27, 2018 - JFLAP 7.1 now available. We have updated JFLAP 7 to Java 8 and made some changes to Turing machines. There is now a difference between a standard Turing machine and a Turing machine in Building Block mode. When opening a standard Turing machine you can decide if you want it converted to Building Block mode so you can add building blocks to it. You cannot convert it back to standard Turing machine. With a standard Turing machine you can run with nondeterminism and run the conversion to an unrestricted grammar. Those do not work in Building Block mode.

• Jan 1, 2018 - JFLAP book is now available as a free download



• July 29, 2016 - JFLAP Modules and Exercises are a comprehensive list of descriptions of JFLAP topics with examples, followed by exercises. This were written by several faculty.



• January 24, 2015 - JFLAP 8.0 BETA is now available. This is a new version of JFLAP that was redesigned and has been under development since 2011. It does not implement all the items from Version 7, but it has some new features that Version 7 did not have. This version is also not as stable as Version 7. Strongly recommend you use Version 7 for a course, with maybe parts from Version 8 if they apply.
  
  New in version 8 Beta include visualization of the CYK Parsing Algorithm, Language generator (generate automatically a specified number of strings for a grammar), redesigned Turing Machine with Building Blocks, more formal definitions displayed with automata and grammars, extension of graphic tools and preference menu, and a new file format.
  
  You can see Ian McMahon's Undergraduate Thesis from May 2014 where he describes many of the new features.
