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