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 optimisation » game optimization, stage optimization, _ optimisation

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

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