# Fulkerson-Preis

Der Fulkerson-Preis (Delbert Ray Fulkerson Prize) ist ein von der Mathematical Programming Society (MPS) und der American Mathematical Society (AMS) alle drei Jahre vergebener Preis für außergewöhnliche Arbeiten in diskreter Mathematik, worunter zum Beispiel Kombinatorik und Informatik fallen. Es werden bis zu drei Preise verliehen, dotiert mit jeweils 1500 Dollar. Sie sind nach Delbert Ray Fulkerson benannt und waren ursprünglich aus einem Fonds finanziert, den Freunde von Fulkerson in seinem Andenken stifteten.
