"Lambda was intended as a company where people with extraordinary intelligence and problem-solving ability (which indeed describes its small staff, and certainly its leader, Everett) would be assigned problems exceeding the usual degree of complexity and challenge. It is such problems that are interesting to such people. The staff included physicists, mathematicians, and chemists (among them were those who had worked in the Manhattan Project). The idea succeeded very well. From recently written memoirs by Joseph George Caldwell, an ex-member of the technical staff of Lambda Corporation who developed there a practical method for applying the famous John Nash solution (for which Nash later received a Nobel Prize), one learns that "Lambda Corporation's specialty was solving constrained optimization problems, especially two-sided optimization problems, such as occur in warfare." Lambda developed the Quick General War Game Simulator for the Department of Defense."
