针对多终端、多边缘服务器场景下异构工业任务的端边协同处理问题,提出一种基于李雅普诺夫优化和深度强化学习的多任务端边迁移算法.首先,以联合优化任务迁移决策、迁移比例和传输功率为目标,充分考虑计算频率、传输功率、长期能耗和任务截止期等约束,构建系统长期平均开销最小化问题;由于问题中长期目标及约束中变量在不同时隙相互耦合,难以求解,基于李雅普诺夫优化理论,将长期平均开销最小化问题解耦为独立时隙的策略优化问题;通过马尔可夫决策过程建模,并采用双层竞争深度神经网络架构,提出基于深度强化学习的多任务迁移算法.实验结果表明,所提算法能够稳定收敛,并在长期能耗约束和任务截止期要求下有效降低系统长期平均开销.

陕西省宜君县的彭村石窟共有三窟。第3窟开凿于5世纪中期至太和十八年(494)孝文帝迁都洛阳前后,主要接受来自首都平城的影响。窟内造像偏瘦,也有可能完成于6世纪初。第1、2窟开凿于北魏迁都洛阳以后的6世纪初期,主要接受来自首都洛阳的影响,有汉式佛与菩萨造型。三窟造像都有十分浓厚的陕西地方风格,是当地艺术家的再创作。造像题材有三佛、弥勒、思维菩萨等,都是当时佛教界流行的坐禅观想修行需要的造像题材。

杭州飞来峰的吴越、北宋、元朝的几幅阿弥陀佛石刻像代表了对佛教西方净土的信仰。通过做功德而往生阿弥陀佛净土,是很多佛教徒的修行目的。这种信仰使信徒们通过遵循佛教教义来潜心修行和做功德,包括制作佛教造像。在飞来峰,雕刻与西方净土相关图像的原始目的主要反映在相关造像铭文题记中。这些造像的历史与宗教背景是基于对阿弥陀佛及其净土的崇拜,是信徒为自己及他人造功德和实践修行之必须。佛教经典可以帮助信徒确定造像题材,并为当时的艺术家提供相关图像的一些基本信息。飞来峰吴越宋元阿弥陀佛像展示了10至14世纪艺术家的审美情趣,其中不乏对前朝艺术风格的继承。到了元朝,为了皇室和蒙古王国的利益,扩展了造像创作的目的,佛教造像更加紧密地服务于国家。
