Multidimensional Neural-Like Growing Networks - A New Type of Neural Network

Author 1: Vitaliy Yashchenko

The present paper describes a new type of neural networks - multidimensional neural-like growing networks. Multidimensional neural-like growing networks are a dynamic structure, which varies depending on the external information received by receptors and the information coming from the effector area to the outside world. Multidimensional receptor-effector neural-like growing networks… Read full abstract & cite →

Memetic Multi-Objective Particle Swarm Optimization-Based Energy-Aware Virtual Network Embedding

Author 1: Ashraf A. Shahin

In cloud infrastructure, accommodating multiple virtual networks on a single physical network reduces power consumed by physical resources and minimizes cost of operating cloud data centers. However, mapping multiple virtual network resources to physical network components, called virtual network embedding (VNE), is known to be NP-hard. With considering energy efficiency… Read full abstract & cite →
