Perhaps you should try some spelling variations:
"modified time approximation algorithm" » "modified time approximation algorithms", "modified one approximation algorithm", "modified _ approximation algorithm", "modified bi1 approximation algorithm", "modified male approximation algorithm"
"modified model solutions algorithm" » "modified model solution algorithm", "modified model evolution algorithm", "modified model evolutionary algorithm", "modified nodal solution algorithm", "modified global solutions algorithm", "modified male solutions algorithm"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified model solutions algorithm") or ("modified time approximation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified model solutions algorithm") OR ("modified time approximation algorithm")).
• Removing quotes may allow a broader search: (( modified model solutions algorithm ) or ( modified time approximation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified model solutions algorithm") or ("modified time approximation algorithm"))*.
