let SI denote the maximum independent set computed on the matrix A(I). One partition-oblivious heuristic to compute v: 1. let I = {0, . . . , m + n − 1}, then v := (SI , I \ SI ) For partition-aware heuristics, let U be the set of uncut indices, C be the set of cut indices; we have three possibilities: 1. we compute SU and have v := (SU , U \ SU , C); 2. we compute SU , SC and have v := (SU , U \ SU , SC , C \ SC ); 3. we compute SU , then we deﬁne U := U \ SU and compute SC∪U , having v := (SU , SC∪U , (C ∪ U ) \ SC∪U ).
