Abstract How to integrate the dimensional information of the problem domain into coevolution is studied. Through the analysis of the outcome characteristics of interactions between individuals, a strict dimension identifying method is proposed. Thus, an efficient and reliable coevolutionary algorithm is designed. It can automatically identify dimensions of the problem by the outcome characteristics between individuals with only the current highest test in each dimension maintained and monotonic progress on all dimensions sustained. In this algorithm, the archive can achieve minimum size to guarantee its practicability. Experimental comparisons demonstrate that the algorithm performs more efficiently than others.
