Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
passive optimization » bayesian optimization, game optimization, policy optimization
method algorithm » mom algorithm
modified passive » modified adaptive
using method » nursing methods, focusing method, using metal
code » core

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( code using method algorithm ) OR ( modified passive optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( code using method algorithm ) or ( modified passive optimization algorithms ))*.
