š Highlights of Scientific Accomplishments
Created foundational theory for repairable flow networks and networks with disturbed flows. Authored the pioneering book in this domain. Proved the dual network theorem for networks with disturbed flows, forming the basis of this theory. Developed a fast algorithm for decongesting flow networks and maximizing throughput flow after component failure. Discovered a fundamental flaw in algorithms for maximizing throughput flow in networks since 1956.
