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

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