Perhaps you should try some spelling variations:
"modified notion optimization algorithmssss" » "modified notion optimisation algorithm", "modified notion optimisation algorithmsss", "modified notion estimation algorithmssss", "modified notion estimation algorithmsss", "modified network optimization algorithmssss", "modified policy optimization algorithmssss", "modified allocation optimization algorithmssss"
"modified _ optimization algorithms" » "modified _ optimisation algorithm", "modified _ estimation algorithms", "modified _ estimation algorithm"

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