This simple program converts non-deterministic finite automaton to deterministic finite automaton using algorithm 2.25 from [1]. Input and default output description of automaton is that used in automatons' descriptions in test/ directory. Automaton's description can also be output in either form of directed graph description in .dot format (GraphViz package) or in VCG format. Automaton's decriptions in these formats can be consequently visualized with appropriate tools.
