31 | 31 | |
| 32 | Use the `nuisfit` executable for tuning. |
| 33 | |
| 34 | The default fitter is `ROOT`'s `MIGRAD` algorithm with hard limits. The executable accepts `-f` to change this behaviour. |
| 35 | |
| 36 | The accepted arguments are specified in `src/Routines/MinimizerRoutines.cxx` and NUISANCE accepts all the currently implemented minimisations in ROOT::Minimizer. |

| 41 | fAllowedRoutines = ("Migrad,Simplex,Combined," |
| 42 | "Brute,Fumili,ConjugateFR," |
| 43 | "ConjugatePR,BFGS,BFGS2," |
| 44 | "SteepDesc,GSLSimAn,FixAtLim,FixAtLimBreak" |
| 45 | "Chi2Scan1D,Chi2Scan2D,Contours,ErrorBands"); |
| 46 | }}} |
| 47 | |
| 48 | Separating options with commas runs them in order, e.g. `-f Simplex,Combined` will first run a `Simplex` minimisation and then propagate those results to a `Combined` minimisation. |
