Complexity Digest wrote a new blog post titled Settlement percolation: A study of building connectivity and poles of inaccessibility

•Spatial clustering is applied to coordinates of the building stock in Germany. •We determine the percolation distance at which a country spanning cluster emerges. •The top five largest holes in that mesh are or were military training areas. •The building density decreases with the clustering threshold following a power-law with an exponent close to 0.75. •The overbuilding is a phenomenon that is beyond the dichotomy of sprawled and compact urban development.   Settlement percolation: A study of building connectivity and poles of inaccessibility Martin Behnisch, Martin Schorcht, Steffen...

Complexity Digest has been successfully networking the complexity community since fall of 1999. It is edited by Dr. Carlos Gershenson, and published by the Instituto de Investigaciones en Matematicas Aplicadas y en Sistemas (IIMAS) and the Centro de Ciencias de la Complejidad (C3) of the Universidad Nacional Autonoma de Mexico (UNAM), the most prestigious university in Latin America and hispanic countries.

Its founding editor was Dr Gottfried Mayer, a member of the complexity community since his residence at the Santa Fe Institute in its early days. He deceased victim of cancer on January, 2009. Until then, the sponsor of ComDig was Dean LeBaron, trustee of SFI and investment commentator. ComDig was created by Gottfried and Dean, and we try to follow their original ideas.

Contributors are welcome to send submissions to

ComDig hopes to be of use to all of the growing number of complexity organizations and supported by them.

ComDig has been distributed by weekly email to a list of people who request copies free of charge. ComDig iss also available through RSS (Real Simple Syndication).

Copies will be made available to organizations who may wish to repost ComDig to their own mailing lists. Some may customize the appearance of the content provided to them.

Readership should range from academics in almost every field to business people who want to know how to use the concepts. From students in search of knowledge to journalists looking for items from this rich field of activity. All are encouraged so long as it is of use to them.
