Shift Finding in Sub-linear Time
We study the following basic pattern matching problem. Consider a "code" sequence c consisting of n bits chosen uniformly at random, and a "signal" sequence x obtained by shifting c (modulo n) and adding noise. The goal is to efficiently recover the shift with high probability. T...
