The degeneracy-order conjecture for the online fixed graph process

Let HH be an arbitrary fixed graph, and let dd be the degeneracy of HH. Write τ(PH,n)\tau({\mathcal P}_H,n) for the first time at which the semi-random graph process contains a copy of HH.

Degeneracy-order conjecture. With high probability,

τ(PH,n)=Θ(n(d1)/d).\tau({\mathcal P}_H,n)=\Theta\left(n^{(d-1)/d}\right).

The paper proves the corresponding upper bound for every fixed graph and the matching lower bound when H=Kd+1H=K_{d+1}. The conjecture asserts that the same order holds for every fixed graph HH.
