WebThe canonical optimization variant of the above decision problem is usually known as the Maximum-Cut Problem or Max-Cut and is defined as: Given a graph G, find a maximum cut. The optimization variant is known to be NP-Hard. The opposite problem, that of finding a minimum cut is known to be efficiently solvable via the Ford–Fulkerson algorithm. WebSep 1, 2024 · As shown by Boykov et al. (2001), minimal graph cuts are a powerful tool for solving discrete optimization problems arising in image analysis and computer vision. The use of minimal graph cuts for deformable image registration was, to our knowledge, first proposed by Tang and Chung (2007).
