Perhaps you should try some spelling variations:
"designed network optimization algorithm" » "designed network optimization algorithms", "designed network optimisation algorithm", "designed network estimation algorithm", "defined network optimization algorithm"
"modified invasive approximation algorithms" » "modified passive 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: (("designed network optimization algorithm") or ("modified invasive approximation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("designed network optimization algorithm") OR ("modified invasive approximation algorithms")).
• Removing quotes may allow a broader search: (( designed network optimization algorithm ) or ( modified invasive approximation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("designed network optimization algorithm") or ("modified invasive approximation algorithms"))*.
