HyperbolicLineSearch An inverse line search, takes a point, adds a step (1/(1+iterations)) and returns it |
|||
DampedLineSearch A damped line search, takes a point and a direction. |
|||
BacktrackingSearch The backtracking algorithm for enforcing Armijo rule |
|||
WolfePowellRule The standard Wolfe-Powell rule for a inexact line search |
|||
