Perhaps you should try some spelling variations:
"modified positive convolution algorithms" » "modified positive evolution algorithm", "modified positive solution algorithm", "modified positive solutions algorithms", "modified passive convolution algorithms", "modified adaptive convolution algorithms"
"modified making methods algorithm" » "modified caging methods algorithm", "modified learning methods algorithm", "modified graining methods 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 positive convolution algorithms") OR ("modified making methods algorithm"))~.
• Removing quotes may allow a broader search: (( modified positive convolution algorithms ) or ( modified making methods algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified positive convolution algorithms") or ("modified making methods algorithm"))*.
