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

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