We describe the two-to-one assignment problem, a problem in between the axial three-index assignment problem and the three-dimensional matching problem, having applications in various domains. For the (relevant) case of decomposable costs satisfying the triangle inequality we provide, on the...

In this note we investigate the computational complexity of the transportation problem with a permutable demand vector, TP-PD for short. In the TP-PD, the goal is to permute the elements of the given integer demand vector b=(b <Subscript>1</Subscript>,…,b <Subscript>n</Subscript>) in order to minimize the overall transportation costs....</subscript></subscript>

In a recent paper [Int J Game Theory (2001) 30:99–106], Chu and Halpern investigated the problem of finding optimal strategies in certain games with common payoffs. This short technical note answers a computational complexity question that was left open in their paper. Copyright...
