Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithm, optimized algorithms
estimation algorithms » estimation algorithm, optimisation algorithm, approximation algorithms
notion estimation » motion estimation
same optimization » game optimization, stage optimization, qoe optimization

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 optimization algorithms ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( notion estimation algorithms ) OR ( same optimization algorithms ))".
• Adding a wildcard symbol may retrieve word variants: (( notion estimation algorithms ) OR ( same optimization algorithms ))*.
