Finite Automata Optimizer

This project Finite Automata Optimizer (Otimizador de Autômatos Finitos) was developed to reduce any NFA (Nondeterministic Finite Automata) to a minimal DFA (Deterministic Finite Automata).

This is a flowchart showing the operation of the application:

Source code:
This source was written in Java language using NetBeans 7.x as IDE and the JUNG library to draw the graphs.
All classes, methods, atributtes, etc. are written in English, but most comments are written in Brazilian Portuguese (as required by the teacher).

This code was co-authored in collaboration with my classmate Guilherme Maganha Moreira.
We can not guarantee that the algorithms are 100% correct, because at the time we wrote this code we are still learning about automata.

Download:
We decided to release our source code under the MIT License.
The JUNG library is licensed under the BSD License and is included in binary form.

Source code is available at GitHub
