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

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

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