For people who come to this post later, below is a very relevant discussion

> I have a few questions: What is the difference in scope between NonlinearSolve.jl and NLSolvers.jl/NLsolve.jl? What are the pros/cons of NonlinearSolve.jl vs NLSolvers.jl/NLsolve.jl? Are there any plans to include the algorithms of SIAMFANLEquations.jl into either/both of NonlinearSolve.jl and NLSolvers.jl/NLsolve.jl? In particular, any plans to include the pseudo-transient continuation solver? Or maybe there are some other versions out there? Are there other packages/solvers I should know ab…

Thanks @briochemc for the reference.
