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