In this note, we investigate the efficiency of the greedy algorithm for the classes of multivariate periodic functions with low mixed smoothness in L-q with regard to the wavelet-type basis. We find that the order of greedy approximation in the case of lowsmoothness is different for some range of parameters. (c) 2005 Elsevier Inc. All rights reserved.
