Graph Coloring Problem is one of the typical NP-hard problems in combinatorial optimization problem.

图着色问题（GCP，Graph Coloring Problem）是经典的NP-Hard组合优化问题之一。

The graph vertex coloring problem is the main topic of graph theory and applied in many fields, which is known as NP-complete problem.

图顶点着色问题存在于丰富的科学和工程应用中，如工序问题、排课表问题、物资储存问题等等，但它却是众所周知的NP-完全问题。

Results showed that the topsoil structure of the CK treatment was dense with little porosity developed, and the soil microstructure was sandy granular fabric - granular fabric. In these treatments using chemical fertilizers only, the soil particles did not form soil structure with little porosity, and the soil microstructures in the N, NP or NPK treatment were observed as prophyropectic fabric-fine sand agglomerplasmic fabric, much better than the CK treatment. In those treatments receiving farm manure alone or farm manure plus chemical fertilizers, the quantity of groundmass increased obviously. The soil had a loosen structure, higher porosity, enriched animal and plant residua, iron-manganese nodules and humus, and more micro-aggregates developed. The soil microstructure of the MNPK treatment was pectized-compacted takyric fabric-intertextic fabric, the best microstructure observed among all the treatments.

结果表明：长期不施肥料的CK处理，土壤耕层结构致密，很少有孔隙发育，土壤微结构为结构较差的碎屑聚积状-沙粒聚积状；长期单施化学肥料，土壤颗粒未形成结构体，少孔隙，土壤微结构主要为斑晶胶凝状－细沙粒聚积状结构，土壤结构比CK处理优；长期施用有机肥或有机无机肥料配施的处理，土壤粗颗粒数量显著增加，结构疏松，孔隙量大，动、植物残体丰富，有铁锰结核和腐殖质的形成和微团聚体的发育，土壤微结构类型以MNPK处理最好，为胶凝紧实状－多孔状结构。

MATERIAL AND METHODS: Oysters were exposed to various NP concentrations (0, 0.025, 0.10, 0.25 and 1.00 mg/L) and DNA damage in hemolymph cells was assessed after 24 h and 48 h.

材料与方法：分别以0、0.025、0.10、0.25和1.00mg/L的NP处理牡蛎24h和48h，检测NP对血淋巴细胞DNA的损伤作用。

It is shown that the cellular and nuclear shapes were heteromorphic. Based on their different shapes of endocrine granules,the NE cells could be categorized into three types.The shape of NE cells in BPH was similar to that of the NP,but the number varied remarkably.

前列腺癌中含NE型癌细胞32例，依据内分泌颗粒的形态不同可分为三种类型，前列腺增生症NE细胞的形态与正常前列腺组织相似，但数量有明显变化。

Because of NP property, we will propose an heuristic algorithm to solve the problem.

由于该问题是NP-完备的，我们给出了一个启发式算法。
