Budget Allocator not working properly for target efficiency

[CMartinovich]

Hi All,
i'm encountering an issue with the target efficiency budget allocator. No matter how high or low the target_value CPA is, the total spend recomendation never surpasses the initial total spend for the simulated period (and so it never reaches the higher CPA values).

I'm running Robyn in the 3.11.1 version in R, and noticed that this particular feature does work well in version 3.10.3 using the exact same data/model/code.

I'll leave the code snippet below and the output recomendations for each Robyn version:

AllocatorCollect <- robyn_allocator( InputCollect = RobynRecreated$InputCollect, OutputCollect = RobynRecreated$OutputCollect, select_model = select_model, scenario = "target_efficiency", target_value = 7, date_range = "last_30", export = TRUE, quiet=FALSE )
