Optimal design of frame structures with mixed categorical and continuous design variables using the Gumbel-Softmax method
Gumbel-Softmax reparameterization lets frame designs with discrete catalog choices be optimized by gradient descent together with continuous variables, cutting required structural solves by orders of magnitude in the tested cases.
