Table 4.
Comparison of running time (in second) of PD-based method and two implementations of the ZM method for different cases of data resolutions: high resolution corresponds to an alphabet size of 90, medium resolution corresponds to an alphabet size of 45, and low resolution corresponds to an alphabet size of 10. This experiment is performed on a Hansung laptop with 2.60 GHz CPU, 500 GB of SSD, and 16 GB of RAM using MATLAB R2021a. The proposed PD-based method has fastest run time overall (bold entries in table).
