Abstract / Description This work presents and validates a silicon-native computational architecture for addressing NP-Hard optimization problems, with a specific focus on the Hamiltonian Path Problem on directed (unilateral) graphs, which constitute one of the most restrictive and computationally demanding problem classes due to asymmetric edge constraints and reduced combinatorial symmetry. Unlike conventional approaches that treat the CPU as a high-level software execution platform, the proposed system models the processor as a physical substrate of logic gates, leveraging strictly bitwise operations and hardware-level nondeterminism arising from real silicon behavior. Key Results • Execution PerformanceDirected Hamiltonian Path instances with N = 63(search space ≈ 10⁸⁷) were solved in 0.116 seconds on a standard commercial mobile processor. • Algorithmic MechanismThe method incorporates hardware race conditions, capacitive noise, and L1 cache timing jitter as controlled entropy sources to facilitate escape from local optima, effectively exploiting non-ideal physical characteristics of silicon rather than abstract randomness. • Problem ClassAll reported results correspond to directed (unilateral) graphs, which are strictly harder than undirected variants due to directionality constraints and reduced path equivalence. • Implementation and PortabilityThe implementation is written in pure C / C-style C++, requires zero dynamic memory allocation, and is suitable for deployment on bare-metal microcontrollers, embedded platforms, and DSP architectures with limited memory availability.
