`x` |
Integer, the simulation number |

`StockPars` |
A list of sampled stock parameters, one list element per stock |

`FleetPars` |
A hierarchical list of sampled fleet parameters, first list level is stock, second is fleet |

`np` |
The number of stocks |

`nf` |
The number of fleets |

`nareas` |
The number of areas |

`maxage` |
The maximum number of modeled ages |

`nyears` |
The number of historical 'spool-up' years (from unfished to now) |

`N` |
An array of stock numbers |

`VF` |
An array of vulnerability |

`FretA` |
An array of retention |

`maxF` |
A numeric value specifying the maximum fishing mortality for any single age class |

`MPA` |
An of spatial closures by year |

`CatchFrac` |
A list of stock-specific fleet fractions of current catch
list |

`bounds` |
Bounds for total q estimation |

`tol` |
A numeric value that is the fraction of machine tolerance (once reduction in objective function steps below this, optimization ends) |

`Rel` |
A list of inter-stock relationships see slot Rel of MOM object class |

`SexPars` |
A list of sex-specific dynamics SSBfrom stock_age |
