An inverse hydrologic optics problem is solved using a recent intrinsic regularization scheme that is coupled to a standard Ant Colony System (ACS). The regularization scheme pre-selects candidate solutions based on their smoothness, quantified by a Tikhonov norm. The Chlorophyll profile is...

The decentralized information processing approach pioneered by Radner and Van Zandt endogenously determines the optimal hierarchy for decision making within an organization. The simplest information processing model is the one-shot problem (one set of information to process) which serves as the...

This paper defines and characterizes essential decentralized networks for calculating the associative aggregate of one or more cohorts of data. A network is essential if it is not possible to eliminate an instruction or manager and still calulate the aggregate of each cohort. We show that for...
