WebJan 3, 2024 · I have set up the optimizer with history_size = 3 and max_iter = 1. After each optimizer.step () call you can print the optimizer state with print (optimizer.state [optimizer._params [0]]) and the length of the old directories which are taken into account in each iteration with print (len (optimizer.state [optimizer._params [0]] ['old_dirs'])). WebJun 11, 2024 · 1 Answer. Sorted by: 48. Basically think of L-BFGS as a way of finding a (local) minimum of an objective function, making use of objective function values and the gradient of the objective function. That level of description covers many optimization methods in addition to L-BFGS though.
