Two semi-online scheduling problems on two uniform machines
This paper considers two semi-online scheduling problems, one with known optimal value and the other with known total sum, on two uniform machines with a machine speed ratio of s ≥ 1. For the first problem, we provide an optimal algorithm for s ∈ [ 1+ √
متن کاملSemi-online scheduling on two uniform processors
In this paper we consider the problem of semi on-line scheduling on two uniform processors, in the case where the total sum of the tasks is known in advance. Tasks arrive one at a time and have to be assigned to one of the two processors before the next one arrives. The assignment cannot be changed later. The objective is the minimization of the makespan. We derive lower bounds and algorithms, ...
متن کاملOptimal Preemptive Online Algorithms for Scheduling with Known Largest Size on Two Uniform Machines
In this paper, we consider the semi-online preemptive scheduling problem with known largest job sizes on two uniform machines. Our goal is to maximize the continuous period of time (starting from time zero) when both machines are busy, which is equivalent to maximizing the minimum machine completion time if idle time is not introduced. We design optimal deterministic semi-online algorithms for ...
متن کاملSemi-Online Scheduling on Two Uniform Machines with Known Optimum Part I: Tight Lower Bounds
This problem is about to schedule a number of jobs of different lengths on two uniform machines with given speeds 1 and s ≥ 1, so that the overall completion time, i.e., the makespan, is earliest possible. We consider a semi-online variant (introduced for equal speeds) by Azar and Regev, where the jobs arrive one after the other, while the scheduling algorithm knows the optimum value of the cor...
متن کاملSemi-Online Scheduling on Two Uniform Machines with Known Optimum Part II: Tight Upper Bounds
We consider a semi-online version of the problem of scheduling a sequence of jobs of different lengths on two uniform machines with given speeds 1 and s. Jobs are revealed one by one (the assignment of a job has to be done before the next job is revealed), and the objective is to minimize the makespan. In the considered variant the optimal offline makespan is known in advance. The most studied ...
