再论簇最小化问题的NP-困难性

NP-hardness of the cluster minimization problem revisited

A. B. Adib

摘要:

重新讨论了“簇极小化问题”的计算复杂性[L. T. Wille和J. Vennik,J.Phys.A18,L419(1985)]。有人认为,原始的NP-硬度证明不适用于物理意义上的成对势,例如那些取决于粒子之间几何距离的势。原问题的几何模拟制定,并提供了一个新的证明,这种潜力的多项式时间转换从单位盘图的独立集问题。这种提法的局限性,并承担更直接的后果集群的数值研究提出了新的子问题。

英文摘要:

The computational complexity of the "cluster minimization problem" is revisited [L. T. Wille and J. Vennik, J. Phys. A 18, L419 (1985)]. It is argued that the original NP-hardness proof does not apply to pairwise potentials of physical interest, such as those that depend on the geometric distance between the particles. A geometric analog of the original problem is formulated, and a new proof for such potentials is provided by polynomial time transformation from the independent set problem for unit disk graphs. Limitations of this formulation are pointed out, and new subproblems that bear more direct consequences to the numerical study of clusters are suggested.
