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