L | Maximum number of BFGS vectors. |
Comments
- /IMPL/NONLIN/2 should be defined.
- If L
=0 or /IMPL/LBFGS/L is not defined,
L = L_A is defined in /IMPL/NONLIN.
When this keyword is defined, the new update vectors are accumulated over the old ones by sliding down the set of vectors loosing the oldest ones.
