[commons-math] 11/13: Adapt input files for "SimplexOptimizerTest"
(unit tests).
This is an automated email from the ASF dual-hosted git repository.
erans pushed a commit to branch master
in repository https://gitbox.apache.org/repos/asf/commons-math.git
commit 1e7bce134ffb400040ac4fd61b2ebce50fea93a4
Author: Gilles Sadowski <gi...@gmail.com>
AuthorDate: Sun Aug 22 02:14:53 2021 +0200
Adapt input files for "SimplexOptimizerTest" (unit tests).
The current tests are "baseline" (2D) cases.
Further work should check degradation with increased dimensionality.
