Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
modified adaptive » modified passive
qoe estimation » pose estimation, _ estimation, cover estimations
modified qoe » modified male, modified _, modified bi1

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified adaptive solution algorithm ) OR ( modified qoe estimation algorithms ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified adaptive solution algorithm ) OR ( modified qoe estimation algorithms ))".
• Adding a wildcard symbol may retrieve word variants: (( modified adaptive solution algorithm ) OR ( modified qoe estimation algorithms ))*.
