Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
adaptive estimation » adaptive ventilation, quantile estimation, adaptive quantization
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 estimation algorithms ) OR ( modified bi1 optimization algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified adaptive estimation algorithms ) OR ( modified bi1 optimization algorithm ))*.
