Abstract

For a number of NP-complete sequencing problems [C], the worst-case performance of heuristics has been bounded relative to optimal performance. The bounds are usually shown to be best in the sense that they are achievable. However, when these bounds are based on a single, pathological example, they are not as informative as might be desired. Such is largely the case with Graham's bound [G] of 4/3- 1/3m on the performance of largest-processing-time- first (LPT) sequencing for the classical problem of minimizing schedule lengths, assuming independent tasks on m ≥ 2 identical processors.
