Abstract :
This paper addresses the topology design of hierarchical Hybrid Fiber-VDSL Access Networks (HFVANs). An efficient strategy is applied to find cost-effective and survivable optical distribution networks with metaheuristics in a short time. A novel metaheuristic with only few parameters, Yin-Yang Optimization (YYO), is proposed to solve this NP-hard problem. Its mathematic modeling and YYO-based algorithms are analyzed in detail. It can be applied to similar backbone network topology designs or other discrete optimization problems. Based on numerical results, the performance of YYO is evaluated and compared with previous studies on other modern metaheuristics.
