Perhaps you should try some spelling variations:
"designed network approximation algorithm" » "designed network approximation algorithms", "defined network approximation algorithm"
"modified invasive evolution algorithm" » "modified invasive solution algorithm", "modified invasive evolutionary algorithm", "modified invasive convolution algorithms", "modified invasive ventilation algorithm", "modified passive evolution algorithm"

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: "((\"designed network approximation algorithm\") OR (\"modified invasive evolution algorithm\"))~".
• Removing quotes may allow a broader search: (( designed network approximation algorithm ) OR ( modified invasive evolution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("designed network approximation algorithm") OR ("modified invasive evolution algorithm"))*.
