Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
objective optimization » multiobjective optimization
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
game estimation » pose estimation, game optimization
modified game » modified male, modified adam

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: (( modified game estimation algorithms ) OR ( modified objective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified game estimation algorithms ) or ( modified objective optimization algorithm ))*.
