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
one approximation » time approximation, _ approximation, rough approximations
modified one » modified male, modified near, modified orca

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified quantile optimization algorithms ) or ( modified one approximation algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified quantile optimization algorithms ) OR ( modified one approximation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( modified quantile optimization algorithms ) or ( modified one approximation algorithms ))*.
