Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
quantile optimization » quantile estimation, quadratic optimization, static optimization
modified quantile » modified adaptive
qoe optimization » game optimization, _ optimization, stage optimization
modified qoe » modified male, modified _, modified bi1

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