The maximum dispersion problem

Fernández, Elena; Kalcsics, Jörg; Nickel, Stefan - In: Omega 41 (2013) 4, pp. 721-730

In the maximum dispersion problem, a given set of objects has to be partitioned into a number of groups. Each object has a non-negative weight and each group has a target weight, which may be different for each group. In addition to meeting the target weight of each group, all objects assigned...
