Perhaps you should try some spelling variations:
"modified df optimization algorithms" » "modified df optimisation algorithm", "modified df estimation algorithms", "modified df estimation algorithm", "modified _ optimization algorithms", "modified qoe optimization algorithms", "modified _ optimisation algorithms", "modified adam optimization algorithms", "modified bi1 optimization algorithms"
"modified adaptive evolution algorithm" » "modified adaptive solution algorithm", "modified adaptive evolutionary algorithm", "modified adaptive convolution algorithms", "modified adaptive ventilation algorithm", "modified passive evolution 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 adaptive evolution algorithm") OR ("modified df optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adaptive evolution algorithm\") OR (\"modified df optimization algorithms\"))*".
• Removing quotes may allow a broader search: (( modified adaptive evolution algorithm ) OR ( modified df optimization algorithms ))*.
