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