Perhaps you should try some spelling variations:
"defined network optimization algorithm" » "defined network optimization algorithms", "defined network optimisation algorithm", "defined network estimation algorithm", "designed network optimization algorithm"
"modified invasive optimized algorithm" » "modified invasive optimized algorithms", "modified invasive optimizer algorithms", "modified passive 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: (("defined network optimization algorithm") OR ("modified invasive optimized algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"defined network optimization algorithm\") OR (\"modified invasive optimized algorithm\"))".
• Removing quotes may allow a broader search: (( defined network optimization algorithm ) OR ( modified invasive optimized algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("defined network optimization algorithm") OR ("modified invasive optimized algorithm"))*.
