You likely can't use this as-is, but this is the backported version of the PROTEIN I'm currently running locally. It significantly outperforms PROTEIN (stronger GP and sampling) and HEBO (cost aware).
Specifically, PROTEIN's failure mode is that it loves boundaries. The core issue is that PROTEIN always picks the argmax, while HEBO picks the argmax every third sample with the other two being exploratory. HEBO therefore does not run into this.
