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