Diet models based on goal programming (GP) are valuable tools in designing diets that comply with nutritional, palatability and cost constraints. Results derived from GP models are usually very ...

We give a branch-and-cut algorithm for solving linear programs (LPs) with continuous separable piecewise-linear cost functions (PLFs). Models for PLFs use continuous variables in special-ordered sets ...

SIAM Journal on Applied Mathematics, Vol. 29, No. 4 (Dec., 1975), pp. 571-581 (11 pages) This paper studies the topology of the minimum cost network, which connects a given set of points in R 2. The ...
