In addition, IGBO was assessed by solving well-known real-world problems. The results of benchmark functions show that the IGBO is very competitive, and superior compared to its competitors in finding the optimal solutions with high convergence and coverage. The results of the studied real ...
Generally, the prestressed concrete design optimization problems are nonlinear because the objective function and most of the constraints are nonlinear functions of the design variables; thus, nonlinear programming procedures are required to be used. Therefore, the Box complex method, which is a non-...
The results and statistical analyses confirm the robustness and efficiency of the Hybrid COASaDE in finding optimal solutions. Furthermore, the applicability of the Hybrid COASaDE was validated through several engineering design problems, where COASaDE outperformed other optimizers in achieving the optimal...
Complex-step (CS) approximation and the first-order reliability method (FORM) are unified in the sensitivity analysis of a probabilistic constraint, which streamlines the setup of optimization problems and enhances their implementation in RBDO. Complex-step approximation utilizes an imaginary number as ...
In addition, the surrounding rock stress of a small clear-distance tunnel is affected by lithology and tunnel excavation mode, so the construction and support structure design of a small clear-distance tunnel face many problems. Complex adjacent tunnels form complex small clear-distance tunnels, ...
