Optimally building spanning graphs in semirandom graph processes
Michael Anastos, Maurício Collares, Joshua Erde +3
The semirandom graph process constructs a graph in a series of rounds, starting with the empty graph on vertices. In each round, a player is offered a vertex chosen uni…

Perfect matchings and loose Hamilton cycles in the semirandom hypergraph model
Michael Molloy, Pawel Pralat, Gregory B. Sorkin
We study the 2-offer semirandom 3-uniform hypergraph model on vertices. At each step, we are presented with 2 uniformly random vertices. We choose any other vertex, thus creati…

Building Hamiltonian Cycles in the Semi-Random Graph Process in Less Than Rounds
Alan Frieze, Pu Gao, Calum MacRury +2
The semi-random graph process is an adaptive random graph process in which an online algorithm is initially presented an empty graph on vertices. In each round, a vertex is…
