@misc{12947, author = {Ralph Lorentzen}, title = {Finding the Set of Measurements Necessary to Reveal the State of a Static System}, abstract = {A static system whose state is a linear combination of a finite set of ground states is considered. Based on the measurement of a set of characteristics we want to make an educated guess of the state of the system. The measurements can be expensive and/or time-consuming, and we would like to avoid making unnecessary ones. So we want to determine which characteristics should be measured. Several approaches to this problem are described. All of them are based on integer linear programming.}, year = {2011}, number = {2011-12}, month = {May}, publisher = {Simula Research Laboratory}, }
