Block coordinate descent for joint delay-energy optimization in multi-hop D2D networks
Kai-Xiang Hu, Jacek Gondzio, Caixia Kou
In multi-hop device-to-device (D2D) networks, the optimization of network-level metrics is particularly difficult due to the tight coupling between network-layer routing and physic…
An exact column generation algorithm for load balancing in capacity sharing networks
Kaixiang Hu, Feilong Huang, Caixia Kou
Capacity sharing networks are typical heterogeneous communication networks widely applied in information and communications technology (ICT) field. In such networks, resources like…
New Lagrangian dual algorithms for solving the continuous nonlinear resource allocation problem
Kaixiang Hu, Caixia Kou, Jianhua Yuan
The continuous nonlinear resource allocation problem (CONRAP) has broad applications in economics, engineering, production and inventory management, and often serves as a subproble…
Mini-Batch Stochastic Conjugate Gradient Algorithms with Minimal Variance
Feifei Gao, Caixia Kou, Yu-Hong Dai
Stochastic gradient descent (SGD) methods have gained widespread popularity for solving large-scale optimization problems. However, the inherent variance in SGD often leads to slow…
