The Power of Genetic Algorithms: what remains of the pMSSM?
  Genetic Algorithms (GAs) are explored as a tool for probing new physics with
high dimensionality. We study the 19-dimensional pMSSM, including experimental
constraints from all sources and assessing the consistency of potential signals
of new physics. We show that GAs excel at making a fast and accurate diagnosis
of the cross-compatibility of a set of experimental constraints in such high
dimensional models. In the case of the pMSSM, it is found that only ${\cal
O}(10^4)$ model evaluations are required to obtain a best fit point in
agreement with much more costly MCMC scans. This efficiency allows higher
dimensional models to be falsified, and patterns in the spectrum identified,
orders of magnitude more quickly. As examples of falsification, we consider the
muon anomalous magnetic moment, and the Galactic Centre gamma-ray excess
observed by Fermi-LAT, which could in principle be explained in terms of
neutralino dark matter. We show that both observables cannot be explained
within the pMSSM, and that they provide the leading contribution to the total
goodness of the fit, with $\chi^2_{\delta a_\mu^{\mathrm{SUSY}}}\approx12$ and
$\chi^2_{\rm GCE}\approx 155$, respectively.
