We construct a nondeterministic analogue to \textbf{APP}, denoted \textbf{NAPP}; which is the set of all real valued functions $f: \{ 0,1 \}^{*} \rightarrow [0,1]$, that are approximable within 1/$k$, by a probabilistic nondeterministic transducer, in time poly($n,1^{k}$). We show that the subset of all Boolean functions in $\mbf{NAPP}$ is exactly ... more >>>
