while trying to launch calibrar using a different algorithm (CMA-ES), it does not create the ix sub-folders, but just i0 the first one (which is empty).
here is the error message

calib<- calibrate(par=rep(NA,11),fn=objfn, method='cmaes', lower=0,
upper=0.001, control=control)
Error in file(con, "r") : cannot open the connection
Calls: calibrate -> .calibrar -> .cmaes

While calibrating using method CMA-ES, pop size = 12, nbcores = 6, maxgen = 3

• only one simulation is run at a time (no folder >i0 )
• the command for launching simulations is repeated 11 times (with name "_i0") although popsize is 12
• moreover although I limited to 3 generations it launched more and if I get it correctly plannes to realise 36 iterations (pop size x max gen)
• finally the fitness function is said to be flat which is weird (the model was previously calibrated and we know the function is responsive in these domain of values)

Hi,
I am still (succesfully) using calibrar to calibrate the ISIS-Fish with the method AHR-ES. I have a question regarding the criteria used to stop the algo. I am afraid it is not documented. Is control$convergence <- 0.001 the stopping criteria ? what does it mean ? that it stops when the objective function does not change by more than 0.001 from one generation to the other ?

Thank you

Hi, Ricardo
I've got an error when running the demo, I'm wondering if someone has the same problem or just myself?
Error in { : task 1 failed - "The'yield'variable is NULL."
Thanks!

Hi, Ricardo
I've also run another code and cannot get it run. I'm wondering if you can help me figure out the problem. I think it also has something to do with calibrar.R.
Thanks a lot!
Yi

copy all that is needed for the calibration

YScalib = Calib_YSomose(path = path.dir)

move to the calibration folder

setwd (YScalib$path)
getwd()
[1] "F:/China_YellowSea_Institute/extdata/calib_demo"

run the calibration script
