Webb27 juni 2024 · Python implementation of the powerful Gauss-Newton optimization method. All the code can be found from my GitHub repo. Background. Here I’m going to present an implementation of the gradient-based optimization algorithm, Gauss-Newton. The implementation is done from scratch using only NumPy as a dependency. Webbare based on the tableau simplex method, using dense matrix algebra. This generally achieves remarkable (from tens to up to a thousand) speedup, but the overall performance is still inferior to a good sparsity-exploiting sequential implementation of the revised simplex method.
