Perhaps you should try some spelling variations:
"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"
"modified objective optimizer algorithms" » "modified objective optimized algorithms", "modified objective optimized algorithm", "modified objective optimization algorithms", "modified objective optimal 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 objective optimizer algorithms") OR ("modified deep convolution algorithms"))~.
• Removing quotes may allow a broader search: (( modified objective optimizer algorithms ) or ( modified deep convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimizer algorithms") or ("modified deep convolution algorithms"))*.
