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

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: (( same ((optimizer algorithms) OR (optimizer algorithmss)) ) OR ( game optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( same ((optimizer algorithms) or (optimizer algorithmss)) ) or ( game optimisation algorithm ))*.
