Nicolas Tancogne-Dejean requested to merge improve_chebyshev_oracle into main May 23, 2024

Description

Improvements for the Chebyshev oracle:

-Average over the batch for the exit criteria

Do not take into account states too close to the lower bound. In particular, the highest eigenvalue is a fix point (-1.0) and hence only produces the maximum order, which can reduce significantly the performances.
