Abstract: Thermal simulation is becoming increasingly critical in modern IC design and manufacturing. Feynman–Kac random walk methods can estimate localized temperatures without solving the global field, but in practical settings without Dirichlet boundaries they require very long paths to control the truncation residual. This paper presents FasterRW, a continuation-value framework for accelerating Feynman–Kac thermal random walks. We prove a stopping-tim
