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