Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
passive optimization » bayesian optimization, game optimization, policy optimization
optimizer algorithms » optimized algorithms, optimized algorithm
modified passive » modified adaptive
modified game » modified male, modified adam

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: (( modified passive optimization algorithms ) OR ( modified game optimizer algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified passive optimization algorithms ) or ( modified game optimizer algorithms ))*.
