Perhaps you should try some spelling variations:
"modified write optimization algorithms" » "modified write optimisation algorithm", "modified write estimation algorithms", "modified write estimation algorithm", "modified game optimization algorithms", "modified qoe optimization algorithms", "modified stage 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.

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