Perhaps you should try some spelling variations:
"modified quantile estimation algorithmssss" » "modified quantile estimation algorithms", "modified quantile estimation algorithm", "modified adaptive estimation algorithmssss"
"modified objective allocation algorithms" » "modified objective estimation algorithms", "modified objective approximation algorithms"

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