Lloyd Max Quantization and Clustering : Part 1
Different.


Lloyd-Max is a special type of scalar quantizer design which is optimized (in terms of MSE) to source pdf. Hence the quantizer is generally non-uniform.
Lloyd's algorithm (and the more generalized LBG algorithm) is a scheme to design vector quantization. More information here and here.


That said, one should note that Lloyd's algorithm for VQ is essentially an extension of the scalar Lloyd-Max quantization to higher dimensions (vectorized sources).
