Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
optimized algorithms » optimizer algorithms
optimized algorithm » optimizer algorithms
post optimization » robust optimization, qoe optimization, policy optimization
same » some

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

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