PS:说下在线算法(online algorithm)和离线(offline algorithm)算法,离线算法也就是知道了所有的输入,根据某些条件来选取最佳策略,而在线算法就是无法预知到后面的输入,只能按照目前的状况来做出下一步的最好决策,在线算法追求的是与离线算法一样的好结果。关于在线算法的详细信息可以看维基。写到后面想起了suit同学的口...

, 这种基于全局信息的决策过程就是离线算法(offline algorithm).
Our first main positive result is an exact algorithm for two machines and job sizes in {1,2}. For jobs sizes in {1,2,3}, we can obtain a \frac43\frac{4}{3} -approximation, which improves on the \frac32\frac{3}{2} -approximation that was previously known for this case. Our ...
Schematic of offline learning + online fine-tuning tasks. Credit: Nair et al. In their study, the researchers studied the limitations of existing models in depth and then devised an algorithm that could overcome these issues. The algorithm they created can achieve satisfactory performance when pre...
