Perhaps you should try some spelling variations:
"modified allocation estimation algorithmss" » "modified allocation estimation algorithm", "modified allocation optimization algorithms", "modified allocation estimation algorithms", "modified allocation optimization algorithmss", "modified allocation optimisation algorithms", "modified motion estimation algorithmss"
"modified network estimation algorithms" » "modified network estimation algorithm", "modified network optimization algorithms", "modified network optimisation algorithm", "certified network estimation algorithms", "defined network estimation algorithms", "modified near estimation algorithms"

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 network estimation algorithms") or ("modified allocation estimation algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified network estimation algorithms") OR ("modified allocation estimation algorithmss")).
• Removing quotes may allow a broader search: (( modified network estimation algorithms ) or ( modified allocation estimation algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified network estimation algorithms") or ("modified allocation estimation algorithmss"))*.
