A tool for mathematicians that want to study the basics of Automata Theory and the concepts of Formal Languages in a comprehensive environment

editor's review




JFLAP is an application created especially for mathematicians and those who want to study various computational problems using Automata Theory.

With this application you are able to analyze nondeterministic finite automata and nondeterministic pushdown automata, as well as multi-tape parsing, Turing machines, several types of grammars and L-systems.

So, if you’re a math buff or really interested in learning about these models and machines then JFLAP is a tool you should consider. It displays a user-friendly interface that makes it very easy to handle.

When you run the application, it greets you with a list of all the models and theories that you can experiment with. Meaningly, Finite Automation, Mealy Machine, Moore Machine, Pushdown Automaton, Turing Machine, Regular Expression, Regular Pumping Lemma and Context-Free Pumping Lemma.

Each of the entry types you select opens a new blank window that you can use to insert all the elements and symbols you need in order to create the model. You are provided with an attribute editor, state and transition creators. When creating a Finite Automaton for example, you get to compare equivalence and highlight nondeterminism. You can also save the current graph payout, move vertices and apply a random layout algorithm.

The application seems to cover nearly all important aspects of Automata Theory and Formal Languages study. It also provides you with the options to enable transitions from Turing Machines final states, as well as to allow stay for tape head on transition.

JFLAP also supports a batch mode that lets you run numerous strings against multiple documents at the same time. Even if you work with large schemas, the window for batch mode is resizable so you can easily choose between a large clear drawing or an accessible table.

With the above to consider and much more to uncover, JFLAP is by all means a comprehensive and practical solution if you’re looking to study the basics of Automata Theory and the concepts of Formal Languages.
