Class ApacheCommonsNonLinearConjugateGradientOptimizer


  • public class ApacheCommonsNonLinearConjugateGradientOptimizer
    extends Solver
    This class is a wrapper for the Apache Commons Math3 Non-Linear Conjugate Gradient Optimizer (https://commons.apache.org/proper/commons-math/).

    NOTE: This solver does not allow any constraints, box constraints of variables are ignored!
