Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithm, optimized algorithms
parameters estimation » parameter estimation, parameter estimates, parameter optimization
estimation algorithms » estimation algorithm, optimisation algorithm, approximation algorithms
game optimization » stage optimization, qoe optimization, market optimization

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

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