Perhaps you should try some spelling variations:
"modified notion approximation algorithms" » "modified network approximation algorithms", "modified time approximation algorithms", "modified one approximation algorithms"
"modified adam evaluation algorithm" » "modified adam evolution algorithm", "modified adam estimation algorithm", "modified adam solution algorithm", "modified load evaluation algorithm", "modified based evaluation algorithm", "modified large evaluation algorithm", "modified df evaluation algorithm", "modified near evaluation algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified notion approximation algorithms") or ("modified adam evaluation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified notion approximation algorithms") OR ("modified adam evaluation algorithm"))*.
• Removing quotes may allow a broader search: (( modified notion approximation algorithms ) or ( modified adam evaluation algorithm ))*.
