Ivan I. Fishchuk,Andrey Kadashchukwe consider two approaches to the problem of minimizing an arbitrary submodular function: one using the ., and one with a combinatorial algorithm. For the important special case of symmetric submodular functions we mention a simpler algorithm in Section 14.5.

(Older machines can only move either horizontally or vertically at a time; in this case the adjusting time is proportional to the ℓ.-distance, the sum of the horizontal and the vertical distance.)

Bin Yi,Kristina Larter,Yaguang Xihe edges correspond to the cables. By Theorem 2.4 the minimal connected spanning subgraphs of a given graph are its spanning trees. So we look for a spanning tree of minimum weight, where we say that a subgraph . of a graph . with weights . : .(.) → ℝ has weight .(.(.))=∑..(.).
