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