A $2.28$-competitive algorithm for online scheduling on identical machines

Abstract Related Papers Cited by
  • Online scheduling on identical machines is investigated in the setting where jobs arrive over time. The goal is to minimize the total completion time. A waiting strategy based online algorithm is designed and is proved to be $2.28$-competitive. The result improves the current best online algorithm from the worse-case prospective.
