Perhaps you should try some spelling variations:
"modified df convolutional algorithms" » "modified df convolution algorithms", "modified df evolution algorithm", "modified df evolutionary algorithm", "modified d convolutional algorithms", "modified deep convolutional algorithms", "modified _ convolutional algorithms", "modified adam convolutional algorithms", "modified bi1 convolutional algorithms"
"modified network optimization algorithm" » "modified network optimization algorithms", "modified network optimisation algorithm", "modified network estimation algorithm", "certified network optimization algorithm", "defined network optimization algorithm", "modified near optimization algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified df convolutional algorithms") OR ("modified network optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified df convolutional algorithms\") OR (\"modified network optimization algorithm\"))".
• Removing quotes may allow a broader search: (( modified df convolutional algorithms ) OR ( modified network optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified df convolutional algorithms") OR ("modified network optimization algorithm"))*.
