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

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("machine learning convolution algorithm") or ("modified objective convolution algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("machine learning convolution algorithm") OR ("modified objective convolution algorithms")).
• Removing quotes may allow a broader search: (( machine learning convolution algorithm ) or ( modified objective convolution algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("machine learning convolution algorithm") or ("modified objective convolution algorithms"))*.
