Perhaps you should try some spelling variations:
"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"
"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.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified deep convolution algorithms") OR ("modified network optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified deep convolution algorithms ) or ( modified network optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified deep convolution algorithms") or ("modified network optimization algorithm"))*.
