Perhaps you should try some spelling variations:
optimization algorithmss » optimization algorithms, optimisation algorithm, estimation algorithm
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
parameter estimation » parameter estimates, parameter optimization
cover optimization » qoe optimization, game optimization

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( cover optimization algorithmss ) or ( parameter estimation algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( cover optimization algorithmss ) OR ( parameter estimation algorithms ))*.
