“…So-called semivectorial bilevel optimization problems, where only p := 1 and K := R + are demanded in (BPP), i.e., only the underlying parametric optimization problem (P(x)) possesses multiple objective functions, provide a much more general model paradigm and have been investigated, e.g., in [8,10,17,19,39,57]. The even more general situation where the objective functions of both decision makers in (BPP) are allowed to be vector-valued has been considered, e.g., in [11,24,25,27,37,50]. For formal completeness, let us also mention that the setting where q := 1 and C := R + hold while the objective function of (BPP) is vector-valued is also reasonable, see e.g.…”
