[docs]class MadMiner: """ The central class to manage parameter spaces, benchmarks, and the generation of events through MadGraph and Pythia. An instance of this class is the starting point of most MadMiner applications. It is typically used in four steps: * Defining the parameter space through `MadMiner.add_parameter` * Defining the benchmarks, i.e. the points at which the squared matrix elements will be evaluated in MadGraph, with `MadMiner.add_benchmark()` or, if operator morphing is used, with `MadMiner.set_benchmarks_from_morphing()` * Saving this setup with `MadMiner.save()` (it can be loaded in a new instance with `MadMiner.load()`) * Running MadGraph and Pythia with the appropriate settings with `MadMiner.run()` or `MadMiner.run_multiple()` (the latter allows the user to combine runs from multiple run cards and sampling points) Please see the tutorial for a hands-on introduction to its methods.

Sets benchmarks, i.e. parameter points that will be evaluated by MadGraph, for a morphing algorithm, and calculates all information required for morphing. Morphing is a technique that allows MadMax to infer the full probability distribution `p(x_i | theta)` for each simulated event `x_i` and any `theta`, not just the benchmarks. The morphing basis is optimized with respect to the expected mean squared morphing weights over the parameter region of interest. If keep_existing_benchmarks=True, benchmarks defined previously will be incorporated in the morphing basis and only the remaining basis points will be optimized. Note that any subsequent call to `set_benchmarks` or `add_benchmark` will overwrite the morphing setup. The correct order is therefore to manually define benchmarks first, using `set_benchmarks` or `add_benchmark`, and then to create the morphing setup and complete the basis by calling `set_benchmarks_from_morphing(keep_existing_benchmarks=True)`. Parameters ---------- max_overall_power : int or tuple of int, optional The maximal sum of powers of all parameters contributing to the squared matrix element.

If n_bases > 1, multiple bases are combined, and the weights for each basis are reduced by a factor 1 / n_bases. Currently only the default choice of 1 is fully implemented. Do not use any other value for now. Default value: 1. include_existing_benchmarks : bool, optional If True, the previously defined benchmarks are included in the morphing basis. In that case, the number of free parameters in the optimization routine is reduced. If False, the existing benchmarks will still be simulated, but are not part of the morphing routine. Default value: True. n_trials : int, optional Number of random basis configurations tested in the optimization procedure.
