Perhaps you should try some spelling variations:
"modified notion optimisation algorithmssssss" » "modified notion optimization algorithms", "modified notion optimization algorithmsssssss", "modified notion estimation algorithmssssss", "modified notion estimation algorithmsssssss", "modified network optimization algorithmssssss"
"modified df optimisation algorithm" » "modified df optimization algorithms", "modified df estimation algorithm", "modified df estimation algorithms", "modified _ optimisation algorithm", "modified _ optimization algorithm", "modified qoe optimization algorithm", "modified adam optimisation algorithm", "modified bi1 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 df optimisation algorithm\") OR (\"modified notion optimisation algorithmssssss\"))~".
• Removing quotes may allow a broader search: (( modified df optimisation algorithm ) OR ( modified notion optimisation algorithmssssss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified df optimisation algorithm") OR ("modified notion optimisation algorithmssssss"))*.
