Membership function playground
Pick a generator and tweak its parameters. The curve is the grade of membership μ(x) ∈ [0,1] across the universe.
Fuzzy set operations
Two fuzzy sets A and B (triangular). Zadeh's standard connectives: union = max, intersection = min, complement = 1−μ, difference = A ∩ Bᶜ.
Fuzzy‑number arithmetic
Two triangular fuzzy numbers. The result is computed with the extension principle (min on the input side, sup over preimages) — watch the spread grow. Try "around 2" + "around 3" = "around 5".
α‑cut & structure explorer
Drag α to slice the set. The α‑cut is { x : μ(x) ≥ α }; support, core, and height fall out of the same machinery.
