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 solution algorithm" » "machine learning evolution algorithm", "machine learning convolution algorithms", "machine learning evolutionary algorithm", "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 solution algorithm") or ("modified objective optimized algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("machine learning solution algorithm") OR ("modified objective optimized algorithms")).
• Removing quotes may allow a broader search: (( machine learning solution algorithm ) or ( modified objective optimized algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("machine learning solution algorithm") or ("modified objective optimized algorithms"))*.
