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 load solution algorithm" » "modified load evolution algorithm", "modified load convolution algorithms", "modified load evolutionary algorithm", "modified adam solution algorithm", "modified near solution algorithm", "modified flour solution algorithm", "modified nodal solution algorithm", "modified global 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 load solution algorithm") or ("modified time approximation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified load solution algorithm") OR ("modified time approximation algorithm")).
• Removing quotes may allow a broader search: (( modified load solution algorithm ) or ( modified time approximation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified load solution algorithm") or ("modified time approximation algorithm"))*.
