Yu-Chi Liu,Donald T-H Tan,Jodhbir S. Mehtaciently transforming the program into an equivalent one. Our results are stated in terms of general sparsity bounds, so any new sparsity results immediately improve our work. Generalizations to mixed integer programs are also discussed.

Hoon Jai Chun,Sang-Yong Seol,Joo Young Chostudied. Second we consider generalized precedence constraints, which include, e.g., deadline constraints. Altogether this leads to a more realistic rescheduling problem. The main result is to show that the problem is polynomial. We discuss how to benefit from the polynomiality result in a machine scheduling environment.

The Future of Capsule Endoscopycase of 0 processing times (.). In addition, we show strong NP-hardness of the case of unit resource requirements and weights (.), thus answering an open question of Gy?rgyi and Kis. We also prove that the schedule corresponding to the Shortest Processing Time First ordering provides a 3/2-approximation for the latter problem.

Arc-Flow Approach for Parallel Batch Processing Machine Scheduling with Non-identical Job Sizesespan on parallel processing machines .. The mathematical model is solved using CPLEX, and computational results show that the proposed models have a better performance than other models in the literature.
