Abstract

In this short note, we consider a graph process recently introduced by Frieze, Krivelevich and Michaeli. In their model, the edges of the complete graph K n ${K}_{n}$ are ordered uniformly at random and are then revealed consecutively to a player called Builder. At every round, Builder must decide if they accept the edge proposed at this round or not. We prove that, for every d 2 $d\ge 2$ , Builder can construct a spanning d $d$ -connected graph after ( 1 + o ( 1 ) ) n log n / 2 $(1+o(1))n\mathrm{log}\unicode{x0200A}n/2$ rounds by accepting ( 1 + o ( 1 ) ) d n / 2 $(1+o(1))dn/2$ edges with probability converging to 1 as n $n\to \infty $ . This settles a conjecture of Frieze, Krivelevich and Michaeli.
