Dijkstra’s algorithm, which was proposed in 1956 by the Dutch computer scientist Edsger Dijkstra, has long been regarded as the textbook solution.

This paper considers factoring integers and finding discrete logarithms, two problems that are generally thought to be hard on classical computers and that have been used as the basis of several ...

The discrete Fourier-cosine transform (cos-DFT), the discrete Fourier-sine transform (sin-DFT) and the discrete cosine transform (DCT) are closely related to the discrete Fourier transform (DFT) of ...
