Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
optimized algorithms » optimizer algorithms, optimization algorithms
policy optimisation » policy optimization, topology optimization
optimized algorithm » optimizer algorithms

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( policy optimisation algorithm ) or ( policy ((optimized algorithm) OR (optimized algorithms)) ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( policy optimisation algorithm ) OR ( policy ((optimized algorithm) OR (optimized algorithms)) )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( policy optimisation algorithm ) or ( policy ((optimized algorithm) OR (optimized algorithms)) ))".
• Adding a wildcard symbol may retrieve word variants: (( policy optimisation algorithm ) or ( policy ((optimized algorithm) OR (optimized algorithms)) ))*.
