## Overview

Automaton DSL with states/start/accept/alphabet headers and `from symbol to` transitions; Mealy outputs as `q0 a q1 / 1`, Moore via `moore:`. Boolean mode takes minterms and don't-cares for a Gray-coded K-map and QM with essential prime implicants and an exact minimum cover.

## Inputs

- **Mode** (select)
- **Automaton definition** (textarea): states: q0 q1 q2 start: q0 accept: q2 alphabet: a b q0 a q0 q0 b q0 q0 ε q1 q1 b q2 q2 a q2 q2 b q2
- **Number of variables (K-map)** (number)
- **Minterms (ON-set)** (text): 0,1,2,5,6,7,8,9,10,14
- **Don't-cares** (text): e.g. 3,11,12
- **Convert NFA to DFA (subset construction)** (checkbox)
- **Minimize DFA (Moore partition refinement)** (checkbox)
- **Convert Mealy ↔ Moore (if outputs given)** (checkbox)

## When to use

- Convert an ε-NFA or NFA into a DFA with subset construction and ε-closures.
- Minimize a DFA with Moore partition refinement or convert Mealy and Moore machines when outputs are provided.
- Minimize a Boolean function using a Gray-coded Karnaugh map and exact Quine-McCluskey coverage.

## How it works

- Select Automata mode or Boolean minimization mode.
- In Automata mode, enter states, start and accepting states, alphabet symbols, and transitions using the supported definition format.
- Enable DFA conversion, DFA minimization, or Mealy↔Moore conversion as needed.
- In Boolean mode, provide the variable count, ON-set minterms, and optional don't-care terms to calculate the minimal SOP.

## Use cases

- Study ε-closures, subset construction, DFA minimization, and state equivalence with every intermediate round visible.
- Check Mealy and Moore output mappings while learning how output-labeled transitions affect machine states.
- Verify digital logic reductions by comparing Karnaugh map groups with Quine-McCluskey prime implicants and the exact minimum cover.

## Frequently asked questions

### What automata formats does the tutor accept?

Use headers for states, start, accept, and alphabet, followed by transitions in the form `from symbol to`. Use ε or eps for epsilon transitions.

### Can it convert an NFA or ε-NFA to a DFA?

Yes. Enable subset construction to calculate ε-closures and construct the corresponding DFA.

### How does DFA minimization work?

The tutor removes unreachable states and applies Moore partition refinement, showing the refinement rounds.

### How are Mealy and Moore machines entered?

Enter Mealy outputs as `q0 a q1 / 1`. Define Moore outputs with a `moore:` declaration such as `moore: q0:0 q1:1`.

### What Boolean minimization inputs are required?

Select 2 to 4 variables, enter the ON-set minterms, and optionally provide don't-care terms. The tutor returns a Karnaugh grouping and an exact minimal SOP cover.
