Perhaps you should try some spelling variations:
"modified network estimation algorithmss" » "modified network estimation algorithms", "modified network estimation algorithm", "modified network optimization algorithms", "modified network optimization algorithmss", "certified network estimation algorithmss", "defined network estimation algorithmss", "modified near 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 network estimation algorithmss") or ("modified allocation optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified network estimation algorithmss") OR ("modified allocation optimization algorithm")).
• Removing quotes may allow a broader search: (( modified network estimation algorithmss ) or ( modified allocation optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified network estimation algorithmss") or ("modified allocation optimization algorithm"))*.
