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 deep convolution algorithms" » "modified deep evolution algorithm", "modified deep solution algorithm", "modified deep convolutional algorithms", "modified delphi convolution algorithms", "modified df convolution algorithms", "modified near convolution algorithms"

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