Perhaps you should try some spelling variations:
"modified allocation optimisation algorithm" » "modified allocation optimization algorithm", "modified allocation optimization algorithms", "modified allocation estimation algorithm", "modified allocation estimation algorithms"
"modified write estimation algorithmss" » "modified write estimation algorithms", "modified write estimation algorithm", "modified write optimization algorithms", "modified risk estimation algorithmss", "modified pose estimation algorithmss"

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 write estimation algorithmss") OR ("modified allocation optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified write estimation algorithmss ) or ( modified allocation optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified write estimation algorithmss") or ("modified allocation optimisation algorithm"))*.
