An age-structured emulator for the individual based energetics model
William de la Mare

2021
The Scientific Committee has sought an age-structured emulation model that mimics the population level characteristics of individual based energetics models (IBEM) to be used in CLA simulation trials without entailing the long runtimes of the IBEM. This paper presents details
of such an emulator that used demographic parameters calculated from the outputs of simulations using the IBEM. This work fulfils the requirements partly funded by a small grant from the IWC. The overall conclusion is that the amount of computation required to calculate the parameters for the emulator from the IBEM is comparable with the amount of computation that would arise from directly including the IBEM in the CLA simulations and hence there is no appreciable gain in efficiency from using the emulation model.
