Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"modified passive convolution algorithms" » "modified passive evolution algorithm", "modified passive solution algorithm", "modified adaptive 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 passive convolution algorithms") OR ("modified notion optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified passive convolution algorithms ) or ( modified notion optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified passive convolution algorithms") or ("modified notion optimization algorithms"))*.
