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

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