Perhaps you should try some spelling variations:
"modified df convolution algorithms" » "modified df evolution algorithm", "modified df solution algorithm", "modified d convolutional algorithms", "modified _ convolution algorithms", "modified adam convolution algorithms", "modified bi1 convolution algorithms"
"modified network optimisation algorithm" » "modified network optimization algorithms", "modified network estimation algorithm", "modified network estimation algorithms", "modified network optimization algorithm", "certified network optimisation algorithm", "defined network optimisation algorithm", "modified near 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 network optimisation algorithm") OR ("modified df convolution algorithms"))~.
• Removing quotes may allow a broader search: (( modified network optimisation algorithm ) or ( modified df convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified network optimisation algorithm") or ("modified df convolution algorithms"))*.
