- W1567187439 abstract "We consider the online competitiveness for scheduling a set of communication jobs (best described in terms of a weighted graph where nodes denote the communication agents and edges denote communication jobs and three weights associated with each edge denote its length, release time, and deadline, respectively), where each node can only send or receive one message at a time. A job is accepted if it is scheduled without interruption in the time interval corresponding to its length between release time and deadline. We want to maximize the sum of the length of the accepted jobs. When an algorithm is not able to preempt (i.e., abort) jobs in service in order to make room for better jobs, previous lower bound shows that no algorithm can guarantee any constant competitive ratio. We examine a natural variant in which jobs can be aborted and each aborted job can be rescheduled from start (called restart). We present simple algorithms under the assumptions on job length: 2-competitive algorithm for unit jobs under the discrete model of time and (6+4√2 ≈ 11:656)-competitive algorithm for jobs of arbitrary length. These upper bounds are compensated by the lower bounds 1.5, 8-Ɛ, respectively." @default.
