  • 简介:在这篇论文,出现在图形处理的一个二阶段的半混血儿流动商店问题被学习。为这个问题,有二台机器M_1和M_2,和一套独立工作J={J_1,J_2,…,J_n}。每J_i由二项任务组成在任务B_i能开始以前,A_i和B_i,和任务A_i必须被完成。而且,任务A_i能为a_i时间单位在M_1上被处理,否则在为′_的M_2上,我预定单位,当任务B_i能仅仅为b_i时间单位在M_2上被处理时。工作和机器在时间零点是可得到的,没有先买权被允许。目的是最小化最大的工作结束时间。这个问题是NP难的,这被显示出。并且apseudo多项式时间最佳的算法被介绍。有2也是的最坏的比率的一个多项式时间近似算法介绍了。
