Perhaps you should try some spelling variations:
quantization algorithms » estimation algorithms
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
passive quantization » adaptive quantization
game optimization » stage optimization, qoe optimization, market optimization
modified passive » modified adaptive
modified game » modified male, modified adam

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified passive quantization algorithms ) OR ( modified game optimization algorithms ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified passive quantization algorithms ) OR ( modified game optimization algorithms ))*.
