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