Perhaps you should try some spelling variations:
estimation algorithmss » estimation algorithm, optimization algorithms
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
robust estimation » robust optimization, pose estimation, risk estimation
qoe estimation » pose estimation, _ estimation, cover estimations

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( qoe estimation algorithms ) OR ( robust estimation algorithmss ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( qoe estimation algorithms ) OR ( robust estimation algorithmss ))*".
