The Journal of the Operational Research Society, Vol. 55, No. 12 (Dec., 2004), pp. 1275-1280 (6 pages) The fixed-charge problem is a non-linear programming problem of practical interest in business ...

The author presents a rapidly convergent algorithm to solve the general portfolio problem of maximizing concave utility functions subject to linear constraints. The algorithm is based on an iterative ...

We leverage insights from machine learning to optimize the tradeoff between bias and variance when estimating economic models using pooled datasets. Specifically, we develop a simple algorithm that ...

Thank you for printing the lively article “A Storied Approach to Operations Research” (Notes from Academe, June 14), about Gene Woolsey of the Colorado School of Mines. ... I was especially struck by ...

Plerixafor, a reversible CXCR4 antagonist, significantly increases the yield of CD34 + peripheral blood cells in randomized studies, thereby enabling more patients to proceed to autologous transplant.

“To me, an algorithm is any piece of automated code that accepts some number of variables and data, [then] uses those variables and data to make decisions. But that’s the boring computer science ...
