Master Automata Theory with Step-by-Step Rigor
Transform abstract formal languages into interactive, visual computations. From NFA powerset constructions to Thompson's syntax trees, explore every transition with complete mathematical transparency.
Step-by-Step Proofs
Inspect intermediate ε-closure calculations, transition tables, and eliminated state equations.
Interactive State Graphs
Drag nodes, adjust edge weights, configure initial/final states, and export blackboard-ready diagrams.
Formal CS Foundations
Faithful implementations of canonical algorithms from Sipser, Hopcroft, and Ullman textbooks.
Automata Conversion Suite
Select an algorithm to begin visual conversion and step-by-step state tracing.
NFA → DFA
Convert non-deterministic automata to deterministic equivalents via powerset subset construction.
ε-NFA → DFA
Eliminate null transitions by computing complete state ε-closures before determinization.
NFA → RegEx
Synthesize closed-form regular expressions from transition graphs using Arden's state elimination.
RegEx → NFA
Parse arbitrary regular expressions into minimal-subgraph NFAs via Thompson's inductive construction.
DFA Minimizer
Compute the unique minimal DFA by identifying indistinguishable states using table-filling equivalence.
PDA → CFG
Derive equivalent context-free grammar production rules [q, X, p] from stack transition specifications.
CFL → CFG
Inspect and simplify Context-Free Grammar productions, terminals, and non-terminal variable sets.
TM → FA
Explore bounded-tape approximations of Turing Machines into regular state machines for decidability analysis.
