(刘亚锋)最优化方法及其在无线通信和信号处理等交叉领域中的应用
刘亚锋与合作者近年来在优化理论与算法和无线通信最优资源分配两个方面取得了一系列研究成果:
(1)优化理论与算法。提炼了一类在机器学习和无线通信等领域有重要应用的复合非凸

(2)无线通信最优资源分配。首次考虑了多用户多输入多输出干扰信道中最大最小准则下的最优资源分配问题,给出了此问题的基本复杂性理论刻画并针对性地设计了有效的算法;填补了本领域一些理论分析的空白和回答了一些公开问题,包括罗智泉(加拿大皇家科学院院士、SIAM会士、IEEE会士)等2008年关于动态谱管理问题复杂性的公开问题以及苏文藻(两届IEEE信号处理学会最佳论文奖获得者、INFORMS优化学会青年学者奖获得者)2010年关于半正定松弛紧性的公开问题。
