Perhaps you should try some spelling variations:
"active learning evolution algorithm" » "active learning evolutionary algorithm", "active learning convolution algorithms", "active learning estimation algorithm", "active learning convolution algorithm", "active learning emotion algorithm", "machine learning evolution algorithm"
"modified objective solution algorithm" » "modified objective evolutionary algorithm", "modified objective allocation algorithm", "modified objective convolution algorithms", "modified objective estimation 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 solution algorithm") OR ("active learning evolution algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective solution algorithm\") OR (\"active learning evolution algorithm\"))".
• Removing quotes may allow a broader search: (( modified objective solution algorithm ) OR ( active learning evolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective solution algorithm") OR ("active learning evolution algorithm"))*.
