Inverse optimisation and linear programming have emerged as crucial instruments in addressing complex decision-making problems where underlying models must be inferred from observed behaviour. At its ...

The matrix M is based on the Pseudo-Hadamard Transform (PHT) in the original SAFER family of ciphers. The matrix M can be realized as a series of 2-PHT butterflies and Armenian Shuffles ( a kind of ...

"Together with the matrix product operator representation of the duality, this allowed us to write this seemingly non-invertible transformation as a unitary quantum circuit," said Lootens. "Since ...
