Gilles updated MATH-1092: ------------------------- Attachment: (was: MATH-1092.patch) > NonLinearConjugateGradientOptimizer's Line search is a gradient search > returns obviously suboptimal point. > ---------------------------------------------------------------------------------------------------------- > > Key: MATH-1092 > URL: https://issues.apache.org/jira/browse/MATH-1092 > Project: Commons Math > Issue Type: Bug > Reporter: Ajo Fod > Attachments: MATH-1092.patch > > > In package : org.apache.commons.math3.optim.nonlinear.scalar.gradient > In a minimization problem, a line search should not return a point where the > value is greater than the values at the edges of the interval. The line > search violates this obvious requirement by focusing solely on solving for > gradient=0 and ignoring the value. > Moreover LineSearchFunction is something that can be used in other contexts, > so perhaps this should be a standalone class. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
