Palette-sparsification conjecture for arbitrary palettes

From papers

Let GG be a graph on nn vertices with maximum degree ΔGD\Delta_G\leq D. Let Γ\Gamma be an arbitrary color set, let SvΓS_v\subseteq\Gamma satisfy Sv=D+1|S_v|=D+1 for every vertex vv, and let each LvL_v be a uniformly random \ell-subset of SvS_v, where

=(1+ε)logn\ell=(1+\varepsilon)\log n

for fixed ε>0\varepsilon>0.

Palette-sparsification conjecture. The graph GG is LL-colorable with high probability.

This is presented as an expected extension of the paper's main theorem and of the Alon–Assadi framework. The source gives no resolution, so the conjecture remains open.
