Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithm, optimized algorithms
quantile optimization » quantile estimation, quadratic optimization, static optimization
estimation algorithms » estimation algorithm, optimisation algorithm, approximation algorithms
passive estimation » pose estimation
modified quantile » modified adaptive
modified passive » modified adaptive

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified passive estimation algorithms ) OR ( modified quantile optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified passive estimation algorithms ) or ( modified quantile optimization algorithms ))*.
