Randomness and Order in the Topology of Settlement Systems
提出一种基于聚落联系频率分布的线性规划方法，用于分析聚落系统的拓扑结构，并将新指标与Geary相邻系数对比，发现其在分析加拿大及假设聚落系统时更具优势。
"The frequency distribution of settlement links forms the basis of a linear programming methodology which can be utilized to analyze the structure of settlement systems. The resulting index of system topology is compared to a more conventional measure, Geary's contiguity coefficient, which may be applied when the problem is conceptualized as one of spatial autocorrelation on a k-color map. The index of linkage similarity that is introduced appears to have a useful advantage over the Geary measure. The Geary and linkage similarity indices are used to examine the topology of four Canadian and two hypothetical settlement systems."
