“…The sensor selection problem arises in various applications, including robotics [HM97], sensor placement for structures [Kam91,KP02], target tracking [WYPE04,IB05], chemical plant control [KP99], and wireless networks [ZG04]. Sensor selection in the context of dynamical systems is studied in, e.g., [GCHM06,KP98,Osh94]. Sensor selection, with a rather different setup from ours, has been studied in sensor network management [REJ + 07], hypothesis testing in a sensor network [DLT02], and discrete-event systems [JKG03].…”
