Exploiting Locality: Approximating Sorting Buffers
The sorting buffers problem is motivated by many applications in manufacturing processes and computer science, among them car-painting and file servers architecture. The input is a sequence of items of various types. All the items must be processed, one by one, by a service station. We are given a random-access sorting buffer with a limited capacity. Whenever a new item arrives it may be moved ...
متن کاملOnline Scheduling for Sorting Buffers
We introduce the online scheduling problem for sorting buffers. A service station and a sorting buffer are given. An input sequence of items which are only characterized by a specific attribute has to be processed by the service station which benefits from consecutive items with the same attribute value. The sorting buffer which is a random access buffer with storage capacity for k items can be...
متن کاملOnline Sorting Buffers on Line
We consider the online scheduling problem for sorting buffers on a line metric. This problem is motivated by an application to disc scheduling. The input to this problem is a sequence of requests. Each request is a block of data to be written on a specified track of the disc. The disc is modeled as a number of tracks arranged on a line. To write a block on a particular track, the scheduler has ...
متن کاملOffline Sorting Buffers on Line
We consider the offline sorting buffers problem. Input to this problem is a sequence of requests, each specified by a point in a metric space. There is a “server” that moves from point to point to serve these requests. To serve a request, the server needs to visit the point corresponding to that request. The objective is to minimize the total distance travelled by the server in the metric space...
متن کاملExploiting Locality in
Temporal reasoning with uncertainty about the ordering of events is important in a wide variety of applications. Previous research shows that the associated decision problems are hard even for very restricted cases. In this paper, we investigate using the temporal locality of events and the spatial locality of state spaces to speed inference. We propose a new perspective for representing cause-...
