# Changing Bases: Multistage Optimization for Matroids and Matchings

@inproceedings{Gupta2014ChangingBM, title={Changing Bases: Multistage Optimization for Matroids and Matchings}, author={Anupam Gupta and Kunal Talwar and Udi Wieder}, booktitle={ICALP}, year={2014} }

This paper is motivated by the fact that many systems need to be maintained continually while the underlying costs change over time. The challenge is to continually maintain near-optimal solutions to an underlying optimization problem, without creating too much churn in the solution itself. We model this as a multistage combinatorial optimization problem where the input is a sequence of cost functions (one for each time step); while we can change the solution from step to step, we incur an… Expand
