🧠 Growth dynamics of untreated meningiomas

A simple Python-3 implementation of the derivative-free Torczon algorithm for nonlinear constrained optimization

Python functions to create N-dimensional mechanical linkages consisting of struts and joints similar to the Strandbeest by Theo Jansen. The scripts allow one to treat the mechanical network of linkages between the struts as a non-linear neural net, which can be optimized to perform different functions. I call this a Rigid Neural Net (RigNN)
