Perhaps you should try some spelling variations:
"modified objective optimized algorithms" » "modified objective optimized algorithm", "modified objective optimizer algorithms", "modified objective optimization algorithms", "modified objective optimal algorithms"
"machine learning evolution algorithm" » "machine learning solution algorithm", "machine learning evolutionary algorithm", "machine learning convolution algorithms", "machine learning convolution algorithm", "machine learning emotion algorithm"

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 evolution algorithm") OR ("modified objective optimized algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"machine learning evolution algorithm\") OR (\"modified objective optimized algorithms\"))".
• Removing quotes may allow a broader search: (( machine learning evolution algorithm ) OR ( modified objective optimized algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("machine learning evolution algorithm") OR ("modified objective optimized algorithms"))*.
