A complexity analysis of parallel scheduling unit-time jobs with in-tree precedence constraints while minimizing the mean flow time
Résumé
This paper deals with a particular scheduling problem. We consider unit-time jobs and in-tree precedence constraints while minimizing the mean flow time. This problem is observed as P| p j = 1, in-tree| C j with the use of the 3-filed notation. To the best of our knowledge, its complexity is still open. Through a reduction from 3-Partition, we show that this problem is strongly N P-hard.
