2019-09-08～Lyapunov optimization

Wireless video caching and dynamic streaming under differentiated quality requirements
主要知识点1：

• Lyapunov optimization
  网络中序列动态状态的优化-->状态趋于稳定
  keywords: dynamic, state, backlog, stability, optimize， control
  通过控制系统状态到稳定值，从而最小化目标值。
• 论文(video optimization)中应用个：
  dynamic user association adaption.
  Specifically, every user has a queue to store the chunks of video. the state of queue changes with the receiving and processing chunks.
