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

You may be able to get more results by adjusting your search query.

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