  8. Show HN: True and4500 FPS Edge Detection at 1K (CPU-only)

    We completely hacked how the CPU processes data using 1024-bit virtual registers. No GPU, no SIMD, just pure integer arithmetic. Paper and details: https://zenodo.org/records/18706964 Free for academic and personal use.…

  9. Show HN: Exact Hamiltonian Path solver (N=63) in 0.11s on mobile ARM (No RAM) (zenodo.org)

    Author here. I implemented a solver that handles Hamiltonian Path (N=63) using strictly bitwise operations and CPU register logic. The claim: It solves sparse/hard instances (N=63, density 0.25) in ~116ms on a…

  10. Show HN: 289x speedup over MLP using Spectral Graphs (zenodo.org)

    We just released a paper proposing a 'Topological Restructuring of AI'. Instead of training deep networks with Backpropagation (which is slow and energy-hungry), we project data onto a fixed Ramanujan Graph (optimal…
