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 network optimized algorithm" » "modified network optimized algorithms", "modified network optimizer algorithms", "certified network optimized algorithm", "defined network optimized algorithm", "modified near optimized algorithm"

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