Perhaps you should try some spelling variations:
"modified notion optimization algorithmss" » "modified notion optimization algorithms", "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion optimization algorithmsss", "modified notion optimisation algorithmss", "modified notion estimation algorithmss", "modified network optimization algorithmss", "modified policy optimization algorithmss", "modified allocation optimization algorithmss"
"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 algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified _ optimization algorithm\") OR (\"modified notion optimization algorithmss\"))".
• Removing quotes may allow a broader search: (( modified _ optimization algorithm ) OR ( modified notion optimization algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified _ optimization algorithm") OR ("modified notion optimization algorithmss"))*.
