The documentation https://julianlsolvers.github.io/Optim.jl/stable/#algo/simulated_annealing/ has ```julia neighbor!(x_proposal::Array, x::Array) ``` so I propose changing the order of `x_proposal` and `x` in the simulated annealing code.
The vector `b` needs to be updated after a new matrix `A` is randomly generated, so I added the line `b = A*x` immediately after `A = FNC.sprandsym(n,density,1e-4);` is called.
