Perhaps you should try some spelling variations:
"modified objective allocation algorithm" » "modified objective estimation algorithm", "modified objective predation algorithm", "modified objective solution algorithm"
"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: (("active learning evolution algorithm") OR ("modified objective allocation algorithm"))~.
• Removing quotes may allow a broader search: (( active learning evolution algorithm ) or ( modified objective allocation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("active learning evolution algorithm") or ("modified objective allocation algorithm"))*.
