A Relational Modeling System for Linear and Integer Programming
Alper Atamtürk, Eric Johnson, Jeff Linderoth, Martin W. P. Savelsbergh · Operations Research · 2000
We discuss an integer linear programming modeling system based on relational algebra. In this system, all modeling related activities, such as model formulation, model instantiation, and model and instance management, are done using simple operations such as selection, projection, and predicated join.
