Inverse problem of minimum cuts
Zhang, Jianzhong; Cai, Mao - In: Mathematical Methods of Operations Research 47 (1998) 1, pp. 51-58
Given a networkN=(V,A,c), a sources εV, a. sinkt εV and somes —t cuts and suppose each element of the capacity vectorc can be changed with a cost proportional to the changes, the inverse problem of minimum cuts we study here is to change the original capacities with the least total cost...

Solving Project Scheduling Problems by Minimum Cut Computations
Möhring, Rolf H.; Schulz, Andreas S.; Stork, Frederik; … - In: Management Science 49 (2003) 3, pp. 330-350
In project scheduling, a set of precedence-constrained jobs has to be scheduled so as to minimize a given objective. In resource-constrained project scheduling, the jobs additionally compete for scarce resources. Due to its universality, the latter problem has a variety of applications in...

A WEIGHTED INVERSE MINIMUM CUT PROBLEM UNDER THE BOTTLENECK TYPE HAMMING DISTANCE
LIU, LONGCHENG; YAO, ENYU - In: Asia-Pacific Journal of Operational Research (APJOR) 24 (2007) 05, pp. 725-736
An inverse optimization problem is defined as follows. Let S denote the set of feasible solutions of an optimization problem P, let c be a specified cost (capacity) vector, and x0 ∈ S. We want to perturb the cost (capacity) vector c to d so that x0 is an optimal solution of P with respect to...

Cluster-exact approximation of spin glass groundstates
Hartmann, Alexander K. - In: Physica A: Statistical Mechanics and its Applications 224 (1996) 3, pp. 480-488
We present a fast (∼ O (N3)) algorithm which calculates groundstates of Ising spin glasses approximately. It works by randomly selecting clusters of spins which exhibit no frustrations. The spins which were not selected, contribute to the local fields of the selected spins. For the...
