Popis: The measure hypothesis is a quantitative strengthening of the $\mathrm {P} \neq \text {NP}$ conjecture which asserts that $\text {NP}$ is a nonnegligible subset of $\text {EXP}$ . Cai et al. (1997) showed that the analogue of this hypothesis in $\mathrm {P}$ is false. In particular, they showed that $\text {NTIME}[n^{1/11}]$ has measure 0 in $\mathrm {P}$ . We improve on their result to show that the class of all languages decidable in nondeterministic sublinear time has measure 0 in $\mathrm {P}$ . Our result is based on DNF width and holds for all four major notions of measure on $\mathrm {P}$ .
