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