WSPT's Competitive Performance for Minimizing the Total Weighted Flow Time: From Single to Parallel Machines
We consider the classical online scheduling problem over single and parallel machines with the objective of minimizing total weighted flow time. We employ an intuitive and systematic analysis method and show that the weighted shortest processing time (WSPT) is an optimal online algorithm with the co...
