# Slot: strategy 


_Search strategy over the decision space (the `space` axes). 'grid' (default) exhaustively evaluates the Cartesian/zip grid of axis points — today's behaviour. 'nsga2' runs an adaptive multi-objective genetic search (pymoo NSGA-II) that returns the non-dominated Pareto front over `objectives`; axes then supply only decision-variable bounds (domain lo/hi), and per-strategy hyper-parameters (population_size, num_generations, seed, reference_point) live in `parameters`. Extensible later to 'random' / 'sobol' / 'cmaes'. Forward-compatible with the planned unified `Search.strategy`._
