Hence, the minimum cut problem is thus simply formulated as the minimization of a discrete 3. energyfunction: minimize x X (i;j)2V2! i;jjx i … Graph cut optimization is a combinatorial optimization method applicable to a family of functions of discrete variables, named after the concept of cut in the theory of flow networks. Thanks to the max-flow min-cut theorem, determining the minimum cut over a graph representing a flow network is equivalent to … See more A pseudo-Boolean function $${\displaystyle f:\{0,1\}^{n}\to \mathbb {R} }$$ is said to be representable if there exists a graph $${\displaystyle G=(V,E)}$$ with non-negative weights and with source and sink nodes See more Graph construction for a representable function is simplified by the fact that the sum of two representable functions $${\displaystyle f'}$$ See more Generally speaking, the problem of optimizing a non-submodular pseudo-Boolean function is NP-hard and cannot be solved in … See more 1. ^ Adding one node is necessary, graphs without auxiliary nodes can only represent binary interactions between variables. 2. ^ Algorithms such as See more The previous construction allows global optimization of pseudo-Boolean functions only, but it can be extended to quadratic functions of discrete variables with a finite number of values, in the form where See more Quadratic functions are extensively studied and were characterised in detail, but more general results were derived also for higher-order … See more • Implementation (C++) of several graph cut algorithms by Vladimir Kolmogorov. • GCO, graph cut optimization library by Olga Veksler and Andrew Delong.
