-----------------------------

             Summary: 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


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 known minima. The line search violates this obvious requirement by focusing solely on the gradient.
