Perhaps you should try some spelling variations:
"certified network approximation algorithm" » "certified network approximation algorithms", "verified network approximation algorithm"
"modified objective allocation algorithm" » "modified objective estimation algorithm", "modified objective evolution algorithm", "modified objective predation algorithm"

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 allocation algorithm") OR ("certified network approximation algorithm"))~.
• Removing quotes may allow a broader search: (( modified objective allocation algorithm ) or ( certified network approximation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective allocation algorithm") or ("certified network approximation algorithm"))*.
