As to the reasonable matching between the resources needed by multi-task and M-dimensional resources offered by multiprocessing nodes, the author offered multiple dimension set partitioning optimization models, defined the function of resource balancing degree and proposed a Multiple Dimension Set Partitioning Load Balancing Resource Optimization Allocation Algorithm, which can optimize to solve the NP problems.

针对多处理群集系统中多个任务处理需要的资源和多个处理节点能够提供的m维资源间的合理匹配问题，给出了多维集合划分问题的优化模型，定义了资源均衡度函数，提出多维集合划分负载均衡资源优化分配算法，通过该算法可以得到资源匹配NP问题的较优解。

One is a large scale nonlinear programming model with equalities, the other is a more complicated NP hard and nonlinear compound 0-1 programming model. It is difficult for the existed algorithms to fulfill the demands of efficiency and size for the above problems. Two corresponding genetic algorithms are presented, in which several suitable genetic operations are constructed to make the optimization search process in the range of feasible solutions.

Methods Cells were maintained in DMEM medium with 10% fetal bovine serum. Five days before the beginning of experiments, the cells were seeded in phenol red-free DMEM medium containing 5% charcoal dextran-treated FBS. The cells were harvested, and seeded in 6-well culture plates or in 75ml flacks. After NP, BisA and DBP treatments for 72h, the cells were harvested, and mRNA and protein expression of PCNA, bcl-2 and bax were detected by reverse transcription-polymerase chain reaction and immunohistochemistry, respectively.
