Perhaps you should try some spelling variations:
"machine learning convolution algorithms" » "machine learning evolution algorithm", "machine learning solution 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: (("machine learning convolution algorithms") OR ("modified objective optimized algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"machine learning convolution algorithms\") OR (\"modified objective optimized algorithm\"))*".
• Removing quotes may allow a broader search: (( machine learning convolution algorithms ) OR ( modified objective optimized algorithm ))*.
