Perhaps you should try some spelling variations:
optimization algorithmss » optimisation algorithm, estimation algorithms, estimation algorithm
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
quantile optimization » quantile estimation, quadratic optimization, static optimization
modified invasive » modified passive
modified quantile » 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 invasive optimization algorithmss ) OR ( modified quantile optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified invasive optimization algorithmss ) or ( modified quantile optimization algorithms ))*.
