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

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: (( sphere optimisation algorithm ) OR ( game ((optimized algorithm) OR (optimizer algorithms)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( sphere optimisation algorithm ) or ( game ((optimized algorithm) OR (optimizer algorithms)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( sphere optimisation algorithm ) or ( game ((optimized algorithm) OR (optimizer algorithms)) ))*.
