LBFGSLineSearchIncomplete

scalation.optimization.quasi_newton.LBFGSLineSearchIncomplete

case class LBFGSLineSearchIncomplete(variableValues: VectorD, functionValue: Double)

The LBFGSLineSearchIncomplete case class describes the incomplete optimization results obtained before an error occurred in the execution of a line search algorithm in the native implementation of the L-BFGS algorithm. This information might be useful for the user to determine the effectiveness of a certain line search algorithm before an error occurred.

Value parameters

functionValue: Objective function value for the variable values obtained after applying the best step found for the searched line before the occurrence of an error in the line search algorithm.
variableValues: VectorD containing the values of the variables after applying the best step found for the searched line before the occurrence of an error in the line search algorithm.
