Abstract In estimation of distribution algorithms (EDAs), the joint probability distribution of high-performance solutions is presented
by a probability model. This means that the priority search areas of the solution space are characterized by the probability
model. From this point of view, an environment identification-based memory management scheme (EI-MMS) is proposed to adapt
binary-coded EDAs to solve dynamic optimization problems (DOPs). Within this scheme, the probability models that characterize
the search space of the changing environment are stored and retrieved to adapt EDAs according to environmental changes. A
diversity loss correction scheme and a boundary correction scheme are combined to counteract the diversity loss during the
static evolutionary process of each environment. Experimental results show the validity of the EI-MMS and indicate that the
EI-MMS can be applied to any binary-coded EDAs. In comparison with three state-of-the-art algorithms, the univariate marginal
distribution algorithm (UMDA) using the EI-MMS performs better when solving three decomposable DOPs. In order to understand
the EI-MMS more deeply, the sensitivity analysis of parameters is also carried out in this paper.
