Arguments

MOM

A multi-fleet multi-stock operating model (class 'MOM')

MPs

A matrix of methods (nstock x nfleet) (character string) of class MP

CheckMPs

Logical to indicate if Can function should be used to check if MPs can be run.

timelimit

Maximum time taken for a method to carry out 10 reps (methods are ignored that take longer)

Hist

Should model stop after historical simulations? Returns a list containing all historical data

ntrials

Maximum of times depletion and recruitment deviations are resampled to optimize for depletion. After this the model stops if more than percent of simulations are not close to the required depletion

fracD

Maximum allowed proportion of simulations where depletion is not close to sampled depletion from OM before model stops with error

CalcBlow

Should low biomass be calculated where this is the spawning biomass at which it takes HZN mean generation times of zero fishing to reach Bfrac fraction of SSBMSY

HZN

The number of mean generation times required to reach Bfrac SSBMSY in the Blow calculation

Bfrac

The target fraction of SSBMSY for calculating Blow

AnnualMSY

Logical. Should MSY statistics be calculated for each projection year? May differ from MSY statistics from last historical year if there are changes in productivity

silent

Should messages be printed out to the console?

PPD

Logical. Should posterior predicted data be included in the MSE object Misc slot?

parallel

Logical. Should the MSE be run using parallel processing?

save_name

Character. Optional name to save parallel MSE list

checks

Logical. Run tests?

control

control options for testing and debugging

Value

A hierarchical list (by stock then fleet) of objects of class MSE
