Optimiser Architecture
	• How do you optimise in 137-dimensional space? – Hard to calculate gradient due to stochastic noise – Use genetic algorithm • Random designs • Mutation • Interpolation • Crossover			• How do you run 3`700`000 simulations? – Distributed computing – Internet-based / FTP – ~130 users active in last week • >75`000 results sent in – Periodically exchange sample results file
