Abstract
We consider the max hypergraph 3-cut problem with limited unbalance (MH3C-LU). The objective is to divide the vertex set of an edge-weighted hypergraph H= (V, E, w) into three disjoint subsets V1, V2, and V3 such that the sum of edge weights cross different parts is maximized subject to | | Vi| - | Vl| | ≤ B (∀ i≠ l∈ { 1 , 2 , 3 }) for a given parameter B. This problem is NP-hard because it includes some well-known problems like the max 3-section problem and the max 3-cut problem as special cases. We formulate the MH3C-LU as a ternary quadratic program and present a randomized approximation algorithm based on the complex semidefinite programming relaxation technique.
