In this setting, we provide upper and lower bounds on the competitive ratio for the online graph coloring problem as a function of the parameters in this model.

We consider an online model where an adversary constructs a set of 2s instances S instead of one single instance. The algorithm knows S and the adversary ...

The algorithm knows [Formula: see text] and the adversary will choose one instance from [Formula: see text] at random to present to the algorithm. We further ...

Abstract. We consider an online model where an adversary constructs a set of 2s instances S instead of one single instance. The algorithm knows S and the ...
