Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
optimized algorithms » optimized algorithm
optimizer algorithms » optimized algorithm
motion optimization » motion estimation, policy optimization, allocation optimization
done » dong, one, don

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

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