In a multivariable design problem, the structure of the single variable can be maintained. The only modification is to insert an...

Introduction The original Ant System (AS) was proposed by Marco Dorigo in 1990. AS has shown its efficiency and simplified concept in...

Retaining walls are fundamental in geotechnical and structural engineering, yet their design often involves conservative assumptions that increase material costs and construction time. As recently studied by Uray et. al (2021), our new AI-driven cantilever retaining wall optimizer transforms this process by combining modern metaheuristic optimization with established soil mechanics and structural principles. What Makes It Different? Instead of relying on trial-and-error or fi

Metaheuristic algorithms often look alike at first glance. They all work with a “population” of solutions, evolve iteratively, and are...
