Complex-Demand Knapsack Problems and Incentives in AC Power Systems

Lan Yu, +1 more
- 10 May 2012 - 
TL;DR: In this article, the authors considered the complex-demand knapsack problem, where each item is associated with a demand as a complex number, rather than a real number often interpreted as weight or size of the item.
