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

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

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