Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
passive optimization » bayesian optimization, policy optimization, stage optimization
game optimization » stage optimization, qoe optimization, market optimization
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 optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified passive optimization algorithms ) or ( modified game optimization algorithms ))*.
