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

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

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