We use semiclassical methods to study closed strings in the modified [Formula Presented] background with constant [Formula Presented] fields. The pointlike closed strings and the stretched closed strings rotating around the big circle of [Formula Presented] are considered. Quantization of these closed string leads to a time-dependent string spectrum, which we argue corresponds to the renormalization-group flow of the dual noncommutative Yang-Mills theory.
