Burman, Chen, Chen, Doty, Nowak, Severson, and Xu [BCC+21a] (PODC) showed that this problem can be solved in $O(n)$ expected time with $O(n)$ states. Recently, G\\k{a}sieniec, Grodzicki, and Stachowiak [GGS25] (PODC) proved that $n+O(\\log n)$ states suffice to achieve $O(n \\log n)$ time both in expectation and with high probability (w.h.p.). If substantially more states are available, sublinear time can be achieved.
