  The increasing complexity of required computational tasks alongside the
inherent limitations in conventional computing calls for disruptive innovation.
LightSolver devised a new quantum-inspired computing paradigm, which utilizes
an all-optical platform for solving hard optimization problems. In this work,
LightSolver introduces its digital simulator and joins the 3-Regular 3-XORSAT
(3R3X) challenge, which aims to map the best available state-of-the-art
classical and quantum solvers. So far, the challenge has resulted in a clear
exponential barrier in terms of time-to-solution (TTS), preventing the
inspected platforms from solving problems larger than a few hundred variables.
LightSolver's simulator is the first to break the exponential barrier,
outperforming both classical and quantum platforms by several
orders-of-magnitude and extending the maximal problem size to more than 16,000
variables.
