In the mathematical fields of graph theory and combinatorial optimization, the bipartite dimension or biclique cover number of a graph ''G'' = (''V'', ''E'') is the minimum number of bicliques (that is complete bipartite subgraphs), needed to cover all edges in ''E''. A collection of bicliques covering all edges in ''G'' is called a biclique edge cover, or sometimes biclique cover. The bipartite dimension of ''G'' is often denoted by the symbol ''d''(''G''). ==Example== An example for a biclique edge cover is given in the following diagrams: Image:Bipartite-dimension-bipartite-graph.svg|A bipartite graph...
