Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
optimized algorithms » optimizer algorithms
policy optimization » topology optimization
optimized algorithm » optimizer 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: (( policy optimization algorithms ) OR ( game ((optimized algorithm) OR (optimized algorithms)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( policy optimization algorithms ) or ( game ((optimized algorithm) OR (optimized algorithms)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( policy optimization algorithms ) or ( game ((optimized algorithm) OR (optimized algorithms)) ))*.
