任务调度优化是多处理器环境(如并行和分布式系统)取得良好性能所面临的最重要挑战之一。目前大多数任务调度算法基于列表调度法,该方法的基本思路是,以列表的形式准备一系列待调度的节点,赋予这些节点不同优先级,然后不断去除列表中优先级最高的节点,并将其分配给具有最早开始时间(Earliest start time,EST)的处理器。由此可见,该算法的完成时间主要由两大因素决定:(1)任务分配顺序的选择(次序子问题);(2)选定顺序的任务如何分配给处理器(分配子问题)。已有文献提出了许多解决次序子问题的好办法,但分配子问题少有人涉及。本文研究结果显示:传统的按照最早开始时间分配任务的方法并非最优;基于蚁群优化算法,得到一种新的方法,可以获得高效得多的调度方案。

Doped polyaniline films were prepared with electrochemistry method. A small conjugated molecule; anthracenecarboxylic acid （2-ACA）, was used as the dopant, considering its electrical activeness due to the conjugated π-π structure. Film morphology of doped and undoped polyaniline samples was investigated. The corresponding changes in optical and electrical properties after ACA doping were discussed. By measuring and calculating their energy level distribution, a promising application of polyaniline thin films as buffer layer in optic-electric devices is expectable.
