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

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