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

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