Perhaps you should try some spelling variations:
quantization algorithms » estimation algorithms
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
adaptive quantization » adaptive ventilation
modified adaptive » modified passive
bi1 optimization » _ optimization, qoe optimization, game optimization
modified bi1 » modified _

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 adaptive quantization algorithms ) OR ( modified bi1 optimization algorithms ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified adaptive quantization algorithms ) OR ( modified bi1 optimization algorithms ))*.
