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