This paper studies the problem how to discover the hierarchies and subtasks automatically during learning process. It can be divided into three steps. Firstly, it uses FCM algorithm based on weighted grid density to classify state spaces. Secondly, it uses unique direction value to find sub-goals set. Finally, it creates the set of options with experience replay. Experimental result shows it can discover sub-goals automatically and quickly which can help agent find an optimal path from start point to end point. © 2013 Binary Information Press.

The efficiency and flexibility of resource allocation has become a major concern in modern data centers recently. For the demand satisfactory under changing application workload, adaptive management of the shared infrastructure via Virtual Machine (VM) replacement is critical to data center providers. In comparison with previous achievements that focus on individual VM behavior, we prefer to take into account both global replacement cost and integrated resource efficiency for a reallocation decision. Motivated by the differences on integrated utilization and replacement quantity obtained from different allocating schemes, in this paper we map such a VM replacement as a dual-objective Vector Packing problem with Minimal Placement Cost (VP-MPC). To solve such a NP hardness problem, we develop an Adaptive VM Replacement (AVR) scheduling mechanism to obtain the approximate optimal VM replacement scheme. AVR is an enhanced grouping genetic algorithm with multi-dimensional awareness and joint optimization based on weighted fuzzy logic. We have implemented our AVR algorithm in CloudSim and make detailed comparisons with several existing studies. The simulation results show that our AVR algorithm achieves high efficiency and exhibits good balance between integrated utilization and global replacement cost. © 2013 by Binary Information Press.
