Optimal linear labelings and eigenvalues of graphsJuvan, Martin ; Mohar, BojanV 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: Preprint series of the Department of Mathematics. - ISSN 0352-3004 (Let. 27, št. 287, 1989, str. 285-299)Type of material - article, component partPublish date - 1989Language - englishCOBISS.SI-ID - 7550553
