K-way hypergraph partitioning has an ever-growing use in parallelization of scientific computing applications. We claim that hypergraph
partitioning with multiple constraints and fixed vertices should be implemented using direct K-way refinement, instead of the widely adopted
recursive bisection paradigm. Our arguments are based on the fact that recursive-bisection-based partitioning algorithms perform considerably
worse when used in the multiple constraint and fixed vertex formulations. We discuss possible reasons for this performance degradation. We
describe a careful implementation of a multi-level direct K-way hypergraph partitioning algorithm, which performs better than a well-known
recursive-bisection-based partitioning algorithm in hypergraph partitioning with multiple constraints and fixed vertices. We also experimentally
show that the proposed algorithm is effective in standard hypergraph partitioning.
