Solution Algorithms =================== .. toctree:: :maxdepth: 1 :caption: Available Solution Methods linear newton modifiednewton newtonlinesearch krylovnewton secantnewton bfgs broyden Algorithms in OpenSees define the solution strategy used to solve the nonlinear equations. They determine how the system is linearized and how the solution is updated. Each algorithm has different characteristics that make it suitable for particular types of problems.
