Spiral Motion Mode Embedded Grasshopper Optimization Algorithm: Design and Analysis

Abstract

A new enhanced grasshopper optimization algorithm (GOA) has been developed and successfully applied to feature selection. GOA, as a heuristic algorithm, is proposed by simulating the living habits of grasshoppers in nature. Although GOA has an excellent global optimization capability, it still faces the disadvantage of low efficiency of searching optimization due to its ease of falling into the local optimum. Hence, based on the original GOA, this study integrates new ideas to reduce the defects to obtain a better global optimization ability. Because of the continuous optimization problem, the features of pursuing the best possible individual of spiral motion have been considered. The spiral motion is integrated into the GOA exploitation search stage, which further expands the diversification and intensification trends' capacities and effectively balances the exploration and exploitation procedures. Intuitively speaking, GOA with spiral search method can find better solutions in the exploration movement process, which is more efficient than the original search method. In the experimental comparison, to verify the proposed SGOA's ability in dealing with global unconstrained and constrained optimization problems, we compared it with other 30 IEEE 2017 benchmark tasks in meta-heuristic algorithms. Then, it is adopted to optimize engineering design and feature selection problems. We can know that the proposed SGOA has a good optimization ability in practical application from the experimental results. Spiral motion mode can significantly improve the original GOA's exploitation and exploration ability, and the proposed SGOA is of great assistance in practical fields.

Intelligent Generation Method and Sustainable Application of Road Systems in Urban Green Spaces: Taking Jiangnan Gardens as an Example

“…Grasshopper is one of the most commonly used parametric software platforms. It can be utilized for visual programming, and it is widely used in the field of design and analysis [ 40 ]. According to the characteristics of classical gardens and the needs of modern landscape design applications, the application’s targets are positioned as three types: courtyards (3000 to 10,000 m 2 ), community parks (10,000 to 20,000 m 2 ), and urban parks (20,000 to 25,000 m 2 ).…”

“…Parameter settings: For VGG-19 and ResNet50 [46], the learning rate is set as 0.01, the dropout is set as 0.1, and some epochs are 8. For the SSG technique [47], the population size is set as 50 and the total iteration is set as 50.…”

Monitoring and Identification of Abnormal Network Traffic by Different Mathematical Models

“…This paper finds the optimal weights and thresholds through the GOA to optimize the BPNN model to obtain the GOA-BPNN model. The principle of the GOA is the predatory behavior of grasshoppers [21]. The process of searching for food is divided into two phases, exploration and exploitation, corresponding to global and local search.…”
