Perhaps you should try some spelling variations:
optimization algorithms » estimation algorithms, estimation algorithm, optimized algorithms
optimisation algorithm » estimation algorithm, estimation algorithms
optimizer algorithms » optimized algorithms, optimized algorithm
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: (( game optimization algorithms ) or ( qoe ((optimisation algorithm) or (optimizer algorithms)) ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( game optimization algorithms ) OR ( qoe ((optimisation algorithm) OR (optimizer algorithms)) )).
• Adding a wildcard symbol may retrieve word variants: (( game optimization algorithms ) or ( qoe ((optimisation algorithm) or (optimizer algorithms)) ))*.
