Median inverse problem and approximating the number of $k$ -median inverses of a permutation

Poly H. da Silva, Arash Jamshidpey, David Sankoff

We introduce the "Median Inverse Problem" for metric spaces. In particular, having a permutation $π$ in the symmetric group $S_{n}$ (endowed with the breakpoint distance), we study t…
