An Analysis of LS Algorithm for the Scheduling Problem on m-2GeneralPurpose Machinery and Two Group Tasks with Uniform Processors[J]. Acta Scientiarum Naturalium Universitatis SunYatseni, 2010,49(6):1-5.DOI:
problem on twogroup jobs with m-2generalpurpose machineries and two specialpurpose machineries that they are the same speed
and the jobs have the setup times and it is no more α time than its processing times is studied. An improved LS algorithm and the upper tight bound performance are given. The ratio of the approximate solution T
LS
and the best way T
*
is (1+α)(2-1/m)
and it is tight for all α.
