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

You may be able to get more results by adjusting your search query.

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