Fig. 1From: Towards negative cycle canceling in wind farm cable layout optimizationDecomposing a side-trip-free walk into cycles. A side-trip-free closed walk W with total costs −1. It can be decomposed into four cycles C1,…,C4. Two of them (C2 and C3) consist of two edges and are discarded. Of the other two, C4 has positive total costs and is discarded as well. The remaining cycle C1 has total costs −2 and is canceledBack to article page
