Abstract | Differential evolution (DE) is confirmed as a simple yet efficacious methodology to solve practical optimization problems. In this paper, we develop a new rotating crossover operator (RCO), to improve the optimization performance by utilizing multiangle searching strategy-based RCO. The proposed crossover scheme, different from conventional crossover operators, can generate trial vectors in control of the self-adaptive crossover parameter and rotation control vectors, which obey Lévy distribution. More specifically, trial vectors are generated diversely within circle regions around donor vectors and target vectors, by multiplying the rotation control vectors and difference of donor and target vectors. Rotation angles and radii are adjusted along with angles and moduli of the rotation control vectors. The proposed RCO operator can be easily applied to crossover strategies of other DE variants with minor changes. In order to verify the efficiency and generality of the algorithm, the proposed RCO scheme is respectively applied to the conventional DE variants and a state-of-the-art algorithm JADE, denoted as JADE-RCO. Further comparison experiments of JADE-RCO and other five efficient DE variants are conducted to confirm the superiority of the improved algorithm JADE-RCO. Series of experiments on a set of test functions in CEC 2013 demonstrate that the DE-RCO shows excellent performance in convergence rate and optimization ability comparing with classic and advanced evolutionary algorithms and it improves the performance of the original algorithms by 57%-96%. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
