Before revision:  It provides an explicit algorithm of how to rewire the corresponding complexes  . Using the concept of genus induction, we construct RNA-RNA interaction complexes of fixed topological genus g uniformly in linear time  .
After revision:  It provides an explicit algorithm of how to rewire the corresponding complexes and an unambiguous decomposition grammar . Using the concept of genus induction, we construct RNA-RNA interaction complexes of fixed topological genus g uniformly in linear time .
