Perhaps you should try some spelling variations:
optimization algorithms » estimation algorithms, estimation algorithm, optimized algorithms
optimisation algorithms » estimation algorithms, estimation algorithm, approximation algorithms
optimisation algorithm » estimation algorithm, estimation algorithms
game optimisation » game optimization, stage optimization, _ optimisation

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

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