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

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

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