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 learning convolution algorithms" » "modified learning evolution algorithm", "modified learning solution algorithm", "mobile learning convolution algorithms", "modified caging convolution algorithms"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified learning convolution algorithms") or ("modified notion optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified learning convolution algorithms") OR ("modified notion optimization algorithms"))*.
• Removing quotes may allow a broader search: (( modified learning convolution algorithms ) or ( modified notion optimization algorithms ))*.
