From personal interest and also on behalf of the Mathematical Programming Society I have been trying to keep afloat in the flood of writing that followed Khachian's "Polynomial Time Algorithm for Linear Programming" (Khachian, L. G. 1979. A polynomial algorithm in linear programming. Dokl. Akad....

This paper deals with a mathematical model designed to provide guidelines for managing a land resource over an extended period of time. We develop a framework which permits sequences of management decisions to be conveniently formulated, and their associated costs and benefits specified. This...
