During the training process, AdaBoost calculates the error rate of weak classifiers based on the current sample weight distribution. It then adjusts the sample weights by increasing the weights of misclassified samples and decreasing the weights of correctly classified samples. This process is ...
This variant is called a binary hybrid equilibrium optimizer (BHEO) and is applied to three common binary optimization problems: 0–1 knapsack, feature selection, and the Merkle–Hellman knapsack cryptosystem (MHKC) to investigate its effectiveness. The experimental findings of BHEO are compared ...

Rihand reservoir is continuously experiencing siltation due to erosion in upper basin; thus study of morphometric-based prioritization of sub-watershed has
The spatial distribution and evolution were analyzed and explored at the regional, urban, and county scales. The results showed that (1) the coordination development level of urbanization in the Guangdong-Hong Kong-Macao Greater Bay Area was gradually increasing. It rapidly increased from 2000 to ...
