Perhaps you should try some spelling variations:
parameters optimization » parameter optimization, parameter estimation
optimization algorithms » optimisation algorithm, estimation algorithms, optimized algorithms
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 algorithm ) OR ( modified parameters optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified game estimation algorithm ) or ( modified parameters optimization algorithms ))*.
