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
code » core

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

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