Primal and dual alternating direction algorithms for ℓ <Subscript>1</Subscript>-ℓ <Subscript>1</Subscript>-norm minimization problems in compressive sensing

Xiao, Yunhai; Zhu, Hong; Wu, Soon-Yi - In: Computational Optimization and Applications 54 (2013) 2, pp. 441-459

In this paper, we propose, analyze and test primal and dual versions of the alternating direction algorithm for the sparse signal reconstruction from its major noise contained observation data. The algorithm minimizes a convex non-smooth function consisting of the sum of ℓ <Subscript>1</Subscript>-norm...</subscript>

A centralized/decentralized design of a full return contract for a risk-free manufacturer and a risk-neutral retailer under partial information sharing

Jeong, In-Jae - In: International Journal of Production Economics 136 (2012) 1, pp. 110-115

We consider the design of full return contract in a simple supply chain with a risk-free manufacturer and a risk-neutral retailer. In this problem, the ordering quantity and the rebate price for unsold products are determined by the retailer and the manufacturer, respectively. We propose an...
