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

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( parameter estimates algorithms ) OR ( game optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( parameter estimates algorithms ) or ( game optimization algorithm ))*.
