Perhaps you should try some spelling variations:
"modified allocation estimation algorithmsss" » "modified allocation estimation algorithm", "modified allocation estimation algorithmss", "modified allocation optimization algorithmsss", "modified allocation optimisation algorithmss", "modified motion estimation algorithmsss"
"modified objective estimation algorithms" » "modified objective estimation algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective allocation algorithms"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective estimation algorithms\") OR (\"modified allocation estimation algorithmsss\"))~".
• Removing quotes may allow a broader search: (( modified objective estimation algorithms ) OR ( modified allocation estimation algorithmsss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective estimation algorithms") OR ("modified allocation estimation algorithmsss"))*.
