Push-Relabel Algoritmen

Push-Relabel Algoritmen, udviklet af Andrew V. Goldberg og Robert E. Tarjan i 1988, er en yderst effektiv metode til at beregne maksimal flow i netværk. I modsætning til metoder baseret på forøgende stier (augmenting path methods), opretholder den et præflow og anvender lokale push- og globale relabeling-operationer til at drive flow mod sænket (sink), hvilket opnår en overlegen worst-case kompleksitet.
