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