Perhaps you should try some spelling variations:
optimization algorithmss » optimisation algorithm, estimation algorithms, estimation algorithm
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
some optimization » game optimization, qoe 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: (( some optimization algorithms ) or ( parameter optimization algorithmss ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( some optimization algorithms ) OR ( parameter optimization algorithmss ))*.
