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