Optimal models of river branching angles in Models in geomorphology.
Derives an optimality model for the geometry of stream junctions and discusses the effects on angles of the two parameters that compose the general optimal angular geometry models.
The AA. demonstrate a new method for obtaining optimal solutions to the Multi-Weber Problem and prove the optimality of the results. The paper seeks to improve implementation of the algorithm to make the solutions economically attractive.
This paper examines the socially optimal (and also equilibrium) locations of two stores or libraries on a linear market of unit length. If each consumer has probability of finding a desired product at each store, then the socially optimal locations
are never completely centralized for full information, but are completely centralized for when costly visit search is necessary. The Nash equilibrium locations of two stores, and various alternative models for the socially optimal locations of two stores
Optimizing the spatial structure of the agricultural production function

The equilibria of optimal production with price elasticity as well as of capital intensity with labor employment determine spatial limits of the optimal production zone which is shifted outward subject to the provision of cheap transportation
. It will help in extending outwardly the optimal spatial limits of capital investment and will mobilize capital resources of farmers in the periphery for efficient and competitive capital-dominated farming.
