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