Lazy Local Search Meets Machine Scheduling
We study the restricted case of Scheduling on Unrelated Parallel Machines. In this problem, we are given a set of jobs J with processing times pj and each job may be scheduled only on some subset of machines Sj ⊆ M . The goal is to find an assignment of jobs to machines to minimize the time by which all jobs can be processed. In a seminal paper, Lenstra, Shmoys, and Tardos [LST87] designed an e...
متن کاملIterated greedy local search methods for unrelated parallel machine scheduling
This work deals with the parallel machines scheduling problem which consists in the assignment of n jobs on m parallel machines. The most general variant of this problem is when the processing time depends on the machine to which each job is assigned to. This case is known as the unrelated parallel machines problem. Similarly to most of the literature, this paper deals with the minimization of ...
متن کاملSolving Parallel Machine Scheduling Problems with Variable Depth Local Search
We present new local search heuristics for the problem of scheduling jobs on identical parallel machines with the goal of minimizing total weighted completion time. Our proposed algorithm is a local search method based on combining a variable number of insertion moves. We develop an efficient heuristic for finding a profitable sequence of insertion moves. In a computational study, we compare th...
متن کاملA Local Search Heuristic for Unrelated Parallel Machine Scheduling with Efficient Neighborhood Search
The parallel mechine scheduling problem with unrelated machines is studied where the objective is to minimize the maximum makespan. In this paper, new local search algorithms are proposed where the neighborhood search of a solution uses the “efficiency” of the machinea for each job. It is shown that this method yields better solutions and shorter running times than the more general local search...
متن کاملLocal Search for Grid Scheduling
This work introduces local search based algorithms as a new technique for the Grid scheduling problem. Specific algorithms based on dispatching rules and local search were proposed and implemented to generate schedule for dynamically arriving jobs. Algorithm performance was compared with typical queue-based algorithms on the basis of objective function optimisation and time required to generate...
