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

• Performing a fuzzy search may retrieve terms with similar spellings: (("active learning convolution algorithm") OR ("modified objective solution algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"active learning convolution algorithm\") OR (\"modified objective solution algorithms\"))".
• Removing quotes may allow a broader search: (( active learning convolution algorithm ) OR ( modified objective solution algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("active learning convolution algorithm") OR ("modified objective solution algorithms"))*.
