Let T be a one-sided property tester for a property P that makes q queries to an input x and,

Accepts with probability 1 if x P, and

Rejects with probability at least 2/3 if x is -far from P.

Convert T to obtain a tester T 0 that makes O(q log 1/) queries and fails with probability at most , i.e., T 0 makes O(q log 1/) to an input x and,

Accepts with probability 1 if x P, and

Rejects with probability at least 1 if x is -far from P.

Let T be a one-sided property tester for a property P that makes a queries to an input : and, Accepts with probability 1 if r EP, and Rejects with probability at least 2/3 if x is e-far from P. Convert T to obtain a tester l' that makes (qlog 1/B) queries and fails with probability at most B, i.e., T' makes (qlog 1/B) to an input x and, Accepts with probability 1 if r EP, and Rejects with probability at least 1 - B if r is e-far from P.
