Such a code is called a (q, c, e) smooth code if there exists a decoding algorithm which while decoding any bit of the input, makes at most q probes on the code word and the probability that it looks at any location is at most c/m. The error made by the decoding algorithm is at most e. Smooth codes were introduced by Katz and Trevisan in connection with Locally decodable codes.\n  For 2-probe smooth codes Kerenedis and de Wolf have shown exponential in n lower bound on m in case c and e are constants.
