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 convolution algorithms" » "modified adaptive evolution algorithm", "modified adaptive solution algorithm", "modified adaptive construction algorithms", "modified adaptive ventilation algorithms", "modified passive convolution algorithms"

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