LBFGSLineSearchFailure
scalation.optimization.quasi_newton.LBFGSLineSearchFailure
case class LBFGSLineSearchFailure(returnCode: LBFGSReturnCode, bestIncompleteResults: LBFGSLineSearchIncomplete)
The LBFGSLineSearchFailure case class describes a failure that occurred in the execution of a line search algorithm in the native implementation of the L-BFGS algorithm. Every line search algorithm used by the native L-BFGS implementation should return an instance of this case class upon encountering an error when searching for the optimal step to take in a given line.
Value parameters
- bestIncompleteResults
-
LBFGSLineSearchIncompleteResultscontaining the best results obtained from the incomplete execution of the line search algorithm. - returnCode
-
LBFGSReturnCodedescribing the error responsible for causing a failure in the line search algorithm. Must be an error code, as returning a non-error code causes undefined behavior.
