Perhaps you should try some spelling variations:
"modified allocation estimation algorithmsss" » "modified allocation estimation algorithms", "modified allocation estimation algorithm", "modified allocation optimization algorithmsss", "modified motion estimation algorithmsss"
"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 allocation estimation algorithmsss"))~.
• Removing quotes may allow a broader search: (( modified objective allocation algorithms ) or ( modified allocation estimation algorithmsss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective allocation algorithms") or ("modified allocation estimation algorithmsss"))*.
