Figure 2From: A minimum-labeling approach for reconstructing protein networks across multiple conditionsThe optimal MKL solution for α = 0.6 is not a minimum Steiner tree over all terminals. In this instance k = 2, T1 = {x, w} and T2 = {y, z}. The black (solid) edges form a Steiner tree with 6 edges and 8 labels, whereas the blue (dashed) edges constitute an MKL solution with 7 edges and 7 labels.Back to article page
