Memory overflow and unexpected shutdown during Constrained Bayesian optimization with multiple objectives

[BinglinW]

Describe the bug Hello, I am a researcher using Bayesian optimization for material preparation. I wrote a Bayesian optimization with constraints, where the optimization is a mixing constraint: x1+x2+... +xn< 1. When the sample size is small (less than 40), the program works fine. Occurs when the sample size is greater than 40, TensorFlow ran out of memory by 10%, which I had solved earlier by switching to a better computer. However, my current sample size is 55. Not only did TensorFlow run out of memory by 10%, but the computer would restart with blue screen.

I would like to know how to fix this problem, for example if it is possible to limit memory usage. Data can be sent privately if needed.

Thanks for reporting this and sorry that it was not noticed for so long! Are you still trying to use trieste or have you given up?
