Maximizing the Spread of Cascades Using Network Design
Proceedings of the 26th Conference on Uncertainty in Artificial Intelligence, PMLR R8:516-525, 2010.
Abstract
We introduce a new optimization framework to maximize the expected spread of cascades in networks. Our model allows a rich set of actions that directly manipulate cascade dy- namics by adding nodes or edges to the net- work. Our motivating application is one in spatial conservation planning, where a cas- cade models the dispersal of wild animals through a fragmented landscape. We propose a mixed integer programming (MIP) formu- lation that combines elements from network design and stochastic optimization. Our ap- proach results in solutions with stochastic op- timality guarantees and points to conserva- tion strategies that are fundamentally differ- ent from naive approaches.
