AlphaChip: Controversy, 2021 Nature paper & Background

AlphaChip is a deep reinforcement learning method for automated chip floorplanning. It was developed at Google and is now a portion of the offerings of the spinoff Ricursive. The basic ideas were introduced in a 2021 paper, which describes an approach to macro placement, a stage of chip floorplanning. It is based on reinforcement learning (RL), a machine…
