Figure 1.

The set R = {r₁,r₂,r₃,r₄} represents the red elements and B = {b₁,b₂,…,b₇} represents the black elements. The selected subsets are S₁ = {r₁,r₂,b₁}, S₂ = {r₃,b₁,b₃}, S₃ = {r₄,b₁,b₄,b₅,b₆}, S₄ = {b₆}, and S₅ = {r₄,b₆,b₇}. All the edges and vertices have capacity one, and the maximum flow is shown in dark blue. As can be seen here, the maximum flow solution reassigns the reads so that three sets/clusters, s1, s2, s3, become multicolor and one set/cluster, s4 becomes empty. Thus, its associated potential SV event will not be among the predicted SV events by our method.
