Abstract

This paper introduces a polynomial blind algorithm that determines when two square matrices, AA and BB, are permutation similar. The shifted and translated matrices (A+βI+γJ)(A+\beta I+\gamma J) and (B+βI+γJ)(B+\beta I+\gamma J) are used to color the vertices of two square, edge weighted, rook's graphs. Then the orbits are found by repeated symbolic squaring of the vertex colored and edge weighted adjacency matrices. Multisets of the diagonal symbols from non-permutation similar matrices are distinct within a few iterations, typically four or less.
