Given a set of positive numbers, an optimal m-partition problem asks for an m-partition optimizing some objective function. List scheduling is an on-line algorithm that has been widely used in scheduling problems. In this paper, we show the tight bounds on the performance of list scheduling for partition problems with the following objective functions: maximizing the minimum part, maximizing the sum of the smallest k parts, minimizing the sum of the largest k parts, and minimizing the ratio of the largest to the smallest part.
