Partition-based algorithms, such as the DIRECT algorithm, are popular algorithms for solving global optimization …-based algorithms which include the DIRECT algorithm as a special case. Then we present a strategy to build the subproblem at the coarse … the original DIRECT algorithm to build a specific global optimization algorithm based on multilevel partition and compare …

a modifed DIRECT algorithm to overcome this shortcoming. The proposed algorithm is proved to be convergent globally …

objective function, while the original DIRECT algorithm is sensitive to linear scaling. Numerical results in this paper show … that DIRECT-a is more robust than the original DIRECT algorithm, which support the theoretical results. Numerical results …

particular, we adopt an improved version of the DIRECT algorithm. Some numerical experimentation confirms the effectiveness of …

considerably better than the previous versions. The algorithms are also compared with the DIRECT algorithm (Jones et al., 1993 …). The comparison shows that the generalized CRS algorithms are better than the DIRECT algorithm in high dimensional problems …
