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