Perhaps you should try some spelling variations:
"modified adaptive optimization algorithms" » "modified adaptive optimisation algorithm", "modified adaptive estimation algorithms", "modified adaptive estimation algorithm", "modified objective optimization algorithms", "modified adaptive quantization algorithms", "modified static optimization algorithms", "modified passive optimization algorithms"
"modified time approximation algorithm" » "modified time approximation algorithms", "modified one approximation algorithm", "modified _ approximation algorithm", "modified bi1 approximation algorithm", "modified male approximation 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 adaptive optimization algorithms") OR ("modified time approximation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adaptive optimization algorithms\") OR (\"modified time approximation algorithm\"))".
• Removing quotes may allow a broader search: (( modified adaptive optimization algorithms ) OR ( modified time approximation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive optimization algorithms") OR ("modified time approximation algorithm"))*.
