François Laferrière commented on MATH-1656: ------------------------------------------- One (first) question: if LocalizedFormats is no more used, It is not practical to extends MathRuntimeException that require Localizable in constructor. Can you provide me with an exemple of new style *Exception. Thanks in advance. > Classical multivariate optimizers (gradient descent, Raphson-Newton, BFGS) > are missing > -------------------------------------------------------------------------------------- > > Key: MATH-1656 > URL: https://issues.apache.org/jira/browse/MATH-1656 > Project: Commons Math > Issue Type: Wish > Components: legacy > Affects Versions: 4.0-beta1 > Reporter: François Laferrière > Priority: Major > Labels: features > Attachments: MATH-1656-GradientDescent-Newton-BFGS-v2.0.zip, > MATH-1658-GradientDescent-Newton-BFGS-v3.0.patch, > MATH-1658-GradientDescent-Newton-BFGS.patch, Screenshot from 2023-07-10 > 12-13-38.png > > > Some classical multivariate such as > * gradient descent, > * Raphson-Newton, > * BFGS > are missing. -- This message was sent by Atlassian Jira (v8.20.10#820010)
