Perhaps you should try some spelling variations:
"modified objective convolution algorithms" » "modified objective evolution algorithm", "modified objective solution algorithm"
"modified orca approximation algorithms" » "modified one approximation algorithms", "modified _ approximation algorithms", "modified time approximation algorithms"

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

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