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 » qoe optimization, stage optimization, smooth optimization
game optimization » stage optimization, qoe optimization, market optimization

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 algorithmss ) or ( game optimization algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( some optimization algorithmss ) OR ( game optimization algorithms ))*.
