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 adaptive evolution algorithm" » "modified adaptive solution algorithm", "modified adaptive evolutionary algorithm", "modified adaptive convolution algorithms", "modified adaptive 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: "((\"defined network optimization algorithm\") OR (\"modified adaptive evolution algorithm\"))~".
• Removing quotes may allow a broader search: (( defined network optimization algorithm ) OR ( modified adaptive evolution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("defined network optimization algorithm") OR ("modified adaptive evolution algorithm"))*.
