LAMBDA: Covering the Solution Set of Black-Box Inequality by Search Space Quantization. (arXiv:2203.13708v1 [cs.LG])

Black-box functions are broadly used to model complex problems that provide
no explicit information but the input and output. Despite existing studies of
black-box function optimization, the solution set satisfying an inequality with
a black-box function plays a more significant role than only one optimum in
many practical situations. Covering as much as possible of the solution set
through limited evaluations to the black-box objective function is defined as
the Black-Box Coverage (BBC) problem in this paper. We formalized this …
