Perhaps you should try some spelling variations:
"modified make optimization algorithms" » "modified make optimisation algorithm", "modified make estimation algorithms", "modified make estimation algorithm", "modified market optimization algorithms", "modified game optimization algorithms", "modified stage optimization algorithms", "modified male optimization algorithms"
"defined network approximation algorithms" » "designed network approximation algorithms"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"defined network approximation algorithms\") OR (\"modified make optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( defined network approximation algorithms ) OR ( modified make optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("defined network approximation algorithms") OR ("modified make optimization algorithms"))*.
