the following code
using CriticalTransitions, Test function meier_stein(u, p, t) # out-of-place x, y = u dx = x - x^3 - 10 * x * y^2 dy = -(1 + x^2) * y [dx, dy] end σ = 0.25 sys = StochSystem(meier_stein, [], zeros(2), σ, idfunc, nothing, I(2), "WhiteGauss") # initial path: parabola xx = range(-1.0, 1.0, length = 30) yy = 0.3 .* (-xx .^ 2 .+ 1) init = Matrix([xx yy]') method = CriticalTransitions.LBFGS() gm = geometric_min_action_method(sys, init, maxiter = 100, method=method) method = "HeymannVandenEijnden" gm = geometric_min_action_method(sys, init, maxiter = 100, method=method)
gives

Yes, sorry that the HeymannVandenEijnden option of gMAM is currently not working. I hope to fix it at some point but for now Optim.jl methods such as the default LBFGS() should be used instead.
HeymannVandenEijnden
