Differentiating through binarized topology changes: Second-order subpixel-smoothed projection
Giuseppe Romano, Rodrigo Arrieta, Steven G. Johnson
A key challenge in topology optimization (TopOpt) is that manufacturable structures, being inherently binary, are non-differentiable, creating a fundamental tension with gradient-b…
