Perhaps you should try some spelling variations:
"modified df optimization algorithm" » "modified df optimization algorithms", "modified df optimisation algorithm", "modified df estimation algorithm", "modified _ optimization algorithm", "modified qoe optimization algorithm", "modified _ optimisation algorithm", "modified adam optimization algorithm", "modified bi1 optimization algorithm"
"modified objective optimized algorithm" » "modified objective optimal algorithm", "modified objective optimization algorithm", "modified objective optimized algorithms", "modified objective optimizer algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified objective optimized algorithm") OR ("modified df optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimized algorithm\") OR (\"modified df optimization algorithm\"))*".
• Removing quotes may allow a broader search: (( modified objective optimized algorithm ) OR ( modified df optimization algorithm ))*.
