Scheduling Problems with Rejection to Minimize the Maximum Flow Time
《Journal of Systems Science & Complexity》2016年第5期1293-1301,共9页ZHANG Liqi LU Lingfa 
supported by the National Nature Science Foundation of China under Grant Nos.11426094,11271338 and U1504103
This paper considers the scheduling problem with rejection on m identical parallel machines to minimize the maximum flow time. The authors show that this problem is NP-hard even when there is a single machine and all ...

EXISTENCE OF 0-1 UNIVERSAL MINIMAL TOTAL DOMINATING FUNCTIONS
《Journal of Systems Science & Complexity》2004年第4期485-491,共7页FANGQizhi 
This research is supported by the National Natural Science Foundation of China (No. 10371114).
In this paper, we study the existence of 0-1 universal minimal total dominating functions in a graph. We establish a formulation of linear inequalities to characterize universal minimal total dominating functions and ...
