Abstract

We study the problem of minimizing, in the preemptive case, the number of late jobs on a single machine (1|pmtn,r"j|@?U"j). This problem can be solved by Lawler's algorithm [E.L. Lawler, Ann. Oper. Res. 26 (1990) 125-133] whose time and space complexities are respectively O(n^5) and O(n^3). We propose a new dynamic programming algorithm whose complexities are respectively O(n^4) and O(n^2).
