Abstract Enterprise Development Optimizer (EDO) is a meta-heuristic algorithm inspired by the enterprise development process with strong global search capability. However, analysis of EDO shows that it suffers from defects rapidly decreasing population diversity and weak exploitation ability when dealing complex optimization problems, while its algorithmic structure has room for further enhancement in process. In order to solve these challenges, this paper proposes multi-strategy optimizer called MSEDO based on basic EDO. A leader-based covariance learning strategy proposed, aiming strengthen quality agents alleviate later stage through guiding role dominant group modifying leader.

The rapid expansion of unmanned aerial vehicle (UAV) applications in complex environments presents significant challenges 3D path planning, particularly overcoming the limitations traditional methods for dynamic obstacle avoidance and computational efficiency. To address these challenges, this study introduces an adaptive whale optimization algorithm (DBO-AWOA), which incorporates chaotic mapping, nonlinear convergence factors, inertia mechanisms, dung beetle optimizer-inspired reproductive behaviors. Specifically, utilizes ICMIC mapping to enhance initial population diversity, a cosine-based factor balance exploration exploitation, hybrid strategy inspired by optimizer mitigate stagnation local optima.

Abstract With the rapid advancement of Unmanned Aerial Vehicle (UAV) technology, trajectory planning has become a focus research. This paper proposes three-dimensional path method for UAV based on an improved Exponential-triangle Optimization Algorithm (IETO). By constructing multi-objective optimization function that considers factors such as length, flight altitude, and turning angle, comprehensive evaluation quality is able to be achieved. The IETO algorithm incorporates interval-constrained logistic chaotic mapping, dynamic reverse learning strategy, adaptive artificial bee colony (ABC) escape mechanism within ETO algorithm. These enhancements prevent premature convergence local optima. Through benchmark tests CEC2017 test set simulations in peak threat environments, demonstrated superior robustness. Compared mainstream algorithms like GWO GJO, achieves best performance 62% tests. It also demonstrates exceptional solving complex functions, effectively balances exploration exploitation capabilities. In mountainous generates smoothest paths with lowest costs quickly converges optimal solution.
