Hypergraph cuts with edge-dependent vertex weights
Applied Network Science, 2022 We develop a framework for incorporating edge-dependent vertex weights (EDVWs) into the hypergraph minimum s-t cut problem. These weights are able to reflect different importance of vertices within a hyperedge, thus leading to better characterized cut ...

Efficient Minimization of Decomposable Submodular Functions [PDF]
, 2010 Many combinatorial problems arising in machine learning can be reduced to the problem of minimizing a submodular function. Submodular functions are a natural discrete analog of convex functions, and can be minimized in strongly polynomial time ...

Maximizing k -Submodular Functions and Beyond [PDF]
ACM Transactions on Algorithms, 2016 We consider the maximization problem in the value oracle model of functions defined on k -tuples of sets that are submodular in every orthant and r -wise monotone, where k ⩾ 2 and 1 ⩽ r ⩽ k .

Multivariate Incomplete Information in the Mixture Model of Contests
The RAND Journal of Economics, Volume 56, Issue 4, Page 607-624, Winter 2025.ABSTRACT A general mixture model of contests is introduced, combining stochastic performance and multivariate incomplete information. Performance is determined by a mixture distribution with endogenous weights on a good and bad distribution, respectively.

Submodular Functions and Perfect Graphs
Mathematics of Operations ResearchWe give a combinatorial polynomial-time algorithm to find a maximum weight independent set in perfect graphs of bounded degree that do not contain a prism or a hole of length four as an induced subgraph. An even pair in a graph is a pair of vertices all induced paths between which are even.

Journal of Economic Surveys, Volume 39, Issue 5, Page 1971-1998, December 2025.ABSTRACT This study reports the results of a systematic literature review on auctions mechanism. Auctions are a very popular practice employed in many fields but does not exist a research that investigates the use of auctions under a cross‐disciplinary approach. This work is focused on analyzing which are the areas where auctions are mostly adopted and

A T2T-Based Offloading Method: Virtual Bank With Movement Prediction
IEEE Access, 2018 Rapid developments in network technologies and mobile devices improve our lives, but the resultant fast-growing traffic leads to a lack of cellular network resources and breaks the balance between profit and costs for network providers.
