We exemplify by mea.s of a.well-known combina.oria. optimiza.ion problem from the kna.sa.k problem fa.ily, i.e., the multidimensiona. multiple-choice kna.sa.k problem （MMKP）.

The phytohormone a.xin is essentia. for pla.t development a.d contributes to nea.ly every a.pect of the pla.t life cycle.

In this review, we provide a.g.a.ce a. very diverse topics of a.xin biolog., such a. biosynthesis, conjug.0}ion, oxida.ion, a.d tra.sport of a.xin. This broa., but certa.nly superficia., overview hig.lig.ts the mutua. importa.ce of a.xin meta.olism a.d tra.sport.
