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

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified write estimation algorithmss") or ("modified allocation optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified write estimation algorithmss") OR ("modified allocation optimization algorithm")).
• Removing quotes may allow a broader search: (( modified write estimation algorithmss ) or ( modified allocation optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified write estimation algorithmss") or ("modified allocation optimization algorithm"))*.
