Abstract
The semi-random graph process is a single player game in which the player is initially presented an empty graph on vertices. In each round, a vertex is presented to the player independently and uniformly at random. The player then adaptively selects a vertex , and adds the edge to the graph. For a fixed monotone graph property, the objective of the player is to force the graph to satisfy this property with high probability in as few rounds as possible. In this paper, we investigate the following three properties: containing a complete graph of order , having the chromatic number at least , and not having an independent set of size at least .
