Optimal linear labelings and eigenvalues of graphsJuvan, Martin ; Mohar, Bojan, 1956-V članku je prikazan polinomski hevristični algoritem za nekatere NP-težke probleme povezane z označitvami grafov. Analizirano je obnašanje algoritma pri določanju pasovnosti, prerezne pasovnosti in ... nekaterih posplošenih pasovnostih grafa. Algoritem uporablja drugo najmanjšo Laplaceovo lastno vrednost grafa in njej pripadajoči lastni vektor. Izpeljane so številne (spektralne) ocene za omejene pasovnosti. Te so nato uporabljene pri analizi algoritma.Source: Discrete applied mathematics. - ISSN 0166-218X (Let. 36, 1992, str. 153-168)Type of material - article, component partPublish date - 1992Language - englishCOBISS.SI-ID - 8169049
