Perhaps you should try some spelling variations:
"modified quantile optimisation algorithms" » "modified quantile optimisation algorithm", "modified quantile optimization algorithms", "modified quantile estimation algorithm", "modified quantile estimation algorithms", "modified adaptive optimisation algorithms"
"modified stochastic estimation algorithms" » "modified stochastic optimization algorithms", "modified stochastic estimation algorithm", "modified stochastic optimisation algorithm"

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 stochastic estimation algorithms") OR ("modified quantile optimisation algorithms"))~.
• Removing quotes may allow a broader search: (( modified stochastic estimation algorithms ) or ( modified quantile optimisation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified stochastic estimation algorithms") or ("modified quantile optimisation algorithms"))*.
