Data Collection for the Sloan Digital Sky Survey—A Network-Flow Heuristic

Robert Lupton, F.Miller Maley, Neal Young
1998 Journal of Algorithms  
The problem is NP-hard in general; the algorithm described is a heuristic, based on Lagriangian-relaxation and min-cost network flow.  ...  The goal of the Sloan Digital Sky Survey is "to map in detail one-quarter of the entire sky, determining the positions and absolute brightnesses of more than 100 million celestial objects".  ...  ACKNOWLEDGMENTS Thanks to Ken Steiglitz for introducing two of the coauthors and to an anonymous referee for helpful suggestions.  ...
