  This study investigates the influence of several bound constraint handling
methods (BCHMs) on the search process specific to Differential Evolution (DE),
with a focus on identifying similarities between BCHMs and grouping patterns
with respect to the number of cases when a BCHM is activated. The empirical
analysis is conducted on the SBOX-COST benchmarking test suite, where bound
constraints are enforced on the problem domain. This analysis provides some
insights that might be useful in designing adaptive strategies for handling
such constraints.
