Can I pause and restart the optimization?

Hi, thank you for this amazing package. I was wondering if there is a way to pause the optimization and save the progress, then restart it? Thank you.

Sorry, this slipped my attention.

Yes, you can use the internal function CMAEvolutionStrategy.run!(o, f), e.g.

function rosenbrock(x)
    n = length(x)
    sum(100 * (x[2i-1]^2 - x[2i])^2 + (x[2i-1] - 1)^2 for i in 1:div(n, 2))
end
result = minimize(rosenbrock, zeros(6), 1., maxfevals = 100)
result.stop.maxfevals = 200
CMAEvolutionStrategy.run!(result, rosenbrock)
