This paper proposes an improved cuckoo search (CS) algorithm combining nonlinear inertial weight and differential evolution (WCSDE) to overcome the shortcomings of CS algorithm, such as low convergence accuracy, lack information exchange within population, inadequate local capabilities. Compared with other variants, two strategies are proposed in this improve properties WCSDE. On one hand, a no...

A teaching-learning-based optimization (TLBO) algorithm is a new population-based algorithm applied in some applications in the literature successfully. Moreover, a genetic algorithm (GA) is a popular tool employed widely in many disciplines of engineering. In this paper, a hybrid GA-TLBO algorithm is proposed for the capacitated three-stage supply chain network design (SCND) problem. The SCND ...
