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