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