Perhaps you should try some spelling variations:
"modified objective approximation algorithm" » "modified objective approximation algorithms"
"modified time solutions algorithms" » "modified time solution algorithm", "modified time evolution algorithm", "modified time convolution algorithms", "modified time evolution algorithms", "modified mild solutions algorithms", "modified bi1 solutions algorithms", "modified male solutions 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 time solutions algorithms") OR ("modified objective approximation algorithm"))~.
• Removing quotes may allow a broader search: (( modified time solutions algorithms ) or ( modified objective approximation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified time solutions algorithms") or ("modified objective approximation algorithm"))*.
