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