I am working on optimization using evolutionary algorithm, specifically SPEA-II. I was curious if there is any algorithm named SPEA-III. I tried googling but I could only find a proposed modification of the SPEA-II using reference search direction. Is it same as SPEA-III, in case of NSGA-III, this is the probably only difference from NSGA-II.
I was able find a reference paper on SPEA3, the authors have proposed what they called a generalization of SPEA2 algorithm and name it as SPEA3.
