Abstract

We present improved algorithms for testing monotonicity of functions. Namely, given the ability to query an unknown function f: Σⁿ ↦ Ξ where Σ and Ξ are finite ordered sets, the test always accepts a monotone f, and rejects f with high probability if it is ϵ-far from being monotone (i.e., every monotone function differs from f on more than an _ fraction of the domain). For any ϵ > 0, the query complexity of the test is O((n=/ϵ) · log |Σ| · log | Ξ |). The previous best known bound was Õ ((n²/ϵ) ·|Σ|). We also present an alternative test for the boolean range Ξ = {0,1} whose query complexity O(n²/ϵ²) is independent of alphabet size |Σ|.
