Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, estimation algorithm, optimized algorithm
optimisation algorithm » optimization algorithms, estimation algorithm
estimation algorithms » estimation algorithm, optimization algorithms, approximation algorithms
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 algorithm ) or ( qoe ((optimisation algorithm) OR (estimation algorithms)) ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( game optimization algorithm ) OR ( qoe ((optimisation algorithm) OR (estimation algorithms)) )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( game optimization algorithm ) or ( qoe ((optimisation algorithm) OR (estimation algorithms)) ))".
• Adding a wildcard symbol may retrieve word variants: (( game optimization algorithm ) or ( qoe ((optimisation algorithm) OR (estimation algorithms)) ))*.
