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