Perhaps you should try some spelling variations:
optimization algorithms » estimation algorithms, estimation algorithm, optimized algorithms
optimization algorithm » estimation algorithm, estimation algorithms, optimized algorithm
optimisation algorithm » estimation algorithm, estimation algorithms
poses optimization » qoe optimization, policy optimization, robust optimization

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( poses optimization algorithms ) or ( _ ((optimization algorithm) or (optimisation algorithm)) ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( poses optimization algorithms ) OR ( _ ((optimization algorithm) OR (optimisation algorithm)) )).
• Adding a wildcard symbol may retrieve word variants: (( poses optimization algorithms ) or ( _ ((optimization algorithm) or (optimisation algorithm)) ))*.
