public static final class Solvers.AdaptiveLinesearchParams extends com.google.protobuf.GeneratedMessageV3 implements Solvers.AdaptiveLinesearchParamsOrBuilder
 At the end of each iteration, regardless of whether the step was accepted
 or not, the adaptive rule updates the step_size as the minimum of two
 potential step sizes defined by the following two exponents.

    • hasStepSizeReductionExponent

      public boolean hasStepSizeReductionExponent()
       The step size reduction exponent defines a step size given by
 (1 - (total_steps_attempted + 1)^(-step_size_reduction_exponent)) *
 step_size_limit where step_size_limit is the maximum allowed step size at
 the current iteration. This should be between 0.1 and 1.
      optional double step_size_reduction_exponent = 1 [default = 0.3];
      Specified by:
      hasStepSizeReductionExponent in interface Solvers.AdaptiveLinesearchParamsOrBuilder
      Returns:
      Whether the stepSizeReductionExponent field is set.
