Var["Variable Order (x1 < x2 < x3)"] --> Table["Unique Table & Computed Cache"]
Table --> ITE["Shannon ITE Expansion: f = v*f1 + ~v*f0"]
ITE --> Canonicity["Canonical Node Identification"]
Canonicity --> Equiv["O(1) Formal Equivalence Verification"]
Features
- 100% Python Standard Library: Pure memoized recursive data structure.
- Canonical Representation: Equivalence checking reduces to pointer/ID equality.
- Complete Boolean Algebra: AND, OR, NOT, XOR, and ITE operations.
