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

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

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