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