Perhaps you should try some spelling variations:
optimization algorithms » estimation algorithms, estimation algorithm, optimized algorithms
optimisation algorithm » estimation algorithm, estimation algorithms
some optimization » game optimization, qoe optimization, stage optimization
_ optimisation » _ optimization

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: (( some optimization algorithms ) OR ( _ optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( some optimization algorithms ) or ( _ optimisation algorithm ))*.
