Perhaps you should try some spelling variations:
"machine learning convolution algorithm" » "machine learning convolution algorithms", "machine learning evolution algorithm", "machine learning solution algorithm"
"modified objective solution algorithms" » "modified objective solution algorithm", "modified objective evolution algorithm", "modified objective convolution algorithms", "modified objective evolutionary algorithms", "modified objective allocation algorithms"

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 solution algorithms") OR ("machine learning convolution algorithm"))~.
• Removing quotes may allow a broader search: (( modified objective solution algorithms ) or ( machine learning convolution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective solution algorithms") or ("machine learning convolution algorithm"))*.
