Szukana fraza: [Abstract = "It was conjectured by Fan and Raspaud \(1994\) that every bridgeless cubic graph contains three perfect matchings such that every edge belongs to at most two of them. We show a randomized algorithmic way of finding Fan\-Raspaud colorings of a given cubic graph and, analyzing the computer results, we try to find and describe the Fan\-Raspaud colorings for some selected classes of cubic graphs"]
