Perhaps you should try some spelling variations:
"modified df convolution algorithms" » "modified df evolution algorithm", "modified df solution algorithm", "modified d convolutional algorithms", "modified _ convolution algorithms", "modified adam convolution algorithms", "modified bi1 convolution algorithms"
"modified objective optimized algorithms" » "modified objective optimized algorithm", "modified objective optimizer algorithms", "modified objective optimization algorithms", "modified objective optimal 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 df convolution algorithms") OR ("modified objective optimized algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified df convolution algorithms\") OR (\"modified objective optimized algorithms\"))*".
• Removing quotes may allow a broader search: (( modified df convolution algorithms ) OR ( modified objective optimized algorithms ))*.
