The submodular system k-partition problem is a problem of partitioning a given finite set V into k non-empty subsets V 1,V 2, ...,V k so that $\sum_{i=1}^k f(V_i)$ is minimized where f is a non-negative submodular function on V, and k is a fixed integer. This problem contains the hypergraph k-cut problem. In this paper, we design the first exact algorithm for k = 3 and approximation algorithms for k 驴 4. We also analyze the approximation factor for the hypergraph k-cut problem.
