Perhaps you should try some spelling variations:
optimization algorithmss » optimisation algorithm, estimation algorithms, estimation algorithm
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
done optimization » qoe optimization, game optimization, stage optimization
parameter » parameters

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

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