Hybridizing two-stage meta-heuristic optimization model with weighted least squares support vector machine for optimal shape of double-arch dams

- Proposing ACOR-PSO as a two-stage meta-heuristic optimization model to efficiently find the optimal shape of double-arch concrete dams.
- The improvement of ACOR-PSO in terms of computational efficiency, optimum solution, stability of results and convergence history in comparison with ACOR and PSO.
- Reducing the computational time of optimization procedure of double-arch dams subject to earthquake loads using weighted least squares support vector machine.
