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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((( _ optimisation algorithm ) or ( _ optimize algorithms ))) or ( qoe optimization algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((( _ optimisation algorithm ) OR ( _ optimize algorithms ))) OR ( qoe optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((( _ optimisation algorithm ) or ( _ optimize algorithms ))) or ( qoe optimization algorithms ))*.
