This is a subproject of SoPhy.
During 2017, we studied a transportation problem with delays on a line graph. The problem can for instance describe inventory control for a set of stores around a setpoint. We showed that the optimal LQ controler is highly structured, can be synthesized efficiently and exactly, and implemented using a simple local communication scheme. We expect that this result can be extended to more general graph structures, and will aim to do so during 2018.
