Minimizing the Makespan for Unrelated Parallel Machines
, 2003
"... In this paper, we study the unrelated parallel machine problem for minimizing the makespan, which is NPhard. We used Simulated Annealing (SA) and Tabu Search (TS) with Neighborhood Search (NS) based on the structure of the problem. We also used a modified SA algorithm, which gives better results th ..."

APPROXIMATION ALGORITHMS FOR SCHEDULING UNRELATED PARALLEL MACHINES
, 1990
"... We consider the following scheduling problem. There are m parallel machines and n independent.jobs. Each job is to be assigned to one of the machines. The processing of.job j on machine i requires time Pip The objective is to lind a schedule that minimizes the makespan. Our main result is a polynomi ..."

Complexity of preemptive minsum scheduling on unrelated parallel machines
 Journal of Algorithms
, 2005
"... We show that the problems of minimizing total completion time and of minimizing the number of late jobs on unrelated parallel machines, when preemption is allowed, are both NPhard in the strong sense. The former result settles a longstanding open question. A special case of the unrelated machine m ..."

Improved Approximation Schemes for Scheduling Unrelated Parallel Machines
 In ACM symposium on Theory of computing
, 1999
"... We consider the problem of scheduling n independent jobs on m unrelated parallel machines, where each job has to be processed by exactly one machine, processing job j on machine i requires p ij time units, and the objective is to minimize the makespan, i.e. the maximum job completion time. Focusing ..."

A Special Case of Scheduling Unrelated Parallel Machines
, 2007
"... We design a 1.75approximation algorithm for a special case of scheduling parallel machines to minimize the makespan, namely the case where each job can be assigned to at most two machines, with the same processing time on either machine. (This is a special case of socalled restricted assignment, w ..."
