Perhaps you should try some spelling variations:
"modified based optimization algorithms" » "modified based optimisation algorithm", "modified based estimation algorithms", "modified based estimation algorithm", "modified game optimization algorithms", "modified market optimization algorithms", "modified qoe optimization algorithms", "modified male optimization algorithms"
"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 based optimization algorithms") or ("modified time approximation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified based optimization algorithms") OR ("modified time approximation algorithms")).
• Removing quotes may allow a broader search: (( modified based optimization algorithms ) or ( modified time approximation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified based optimization algorithms") or ("modified time approximation algorithms"))*.
