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

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 algorithm") OR ("modified notion optimization algorithmssssss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified _ optimization algorithm\") OR (\"modified notion optimization algorithmssssss\"))".
• Removing quotes may allow a broader search: (( modified _ optimization algorithm ) OR ( modified notion optimization algorithmssssss )).
• Adding a wildcard symbol may retrieve word variants: (("modified _ optimization algorithm") OR ("modified notion optimization algorithmssssss"))*.
