Perhaps you should try some spelling variations:
"machines learning convolution algorithm" » "machines learning convolution algorithms", "machines learning evolution algorithm", "machines learning solution algorithm", "machine learning convolution algorithm", "active learning convolution algorithm", "mapping learning convolution algorithm"
"modified objective estimation algorithm" » "modified objective optimization algorithm", "modified objective allocation algorithm"

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

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