Perhaps you should try some spelling variations:
"modified quantile estimation algorithms" » "modified quantile estimation algorithm", "modified quantile optimization algorithms", "modified quantile optimisation algorithm", "modified adaptive estimation algorithms"
"modified positive solutions algorithm" » "modified positive solution algorithm", "modified positive evolution algorithm", "modified positive evolutionary algorithm", "modified passive solutions algorithm", "modified adaptive solutions 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 quantile estimation algorithms") OR ("modified positive solutions algorithm"))~.
• Removing quotes may allow a broader search: (( modified quantile estimation algorithms ) or ( modified positive solutions algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified quantile estimation algorithms") or ("modified positive solutions algorithm"))*.
