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 time convolution algorithms" » "modified time evolution algorithm", "modified time solution algorithm", "modified time evolution algorithms", "modified bi1 convolution algorithms", "modified male 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 time convolution algorithms") or ("modified notion optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified time convolution algorithms") OR ("modified notion optimization algorithms")).
• Removing quotes may allow a broader search: (( modified time convolution algorithms ) or ( modified notion optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified time convolution algorithms") or ("modified notion optimization algorithms"))*.
