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 allocation estimation algorithms" » "modified allocation optimization algorithms", "modified motion estimation algorithms", "modified allocation estimation algorithm", "modified allocation optimisation algorithm"

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 allocation estimation algorithms") OR ("modified deep convolution algorithms"))~.
• Removing quotes may allow a broader search: (( modified allocation estimation algorithms ) or ( modified deep convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified allocation estimation algorithms") or ("modified deep convolution algorithms"))*.
