Perhaps you should try some spelling variations:
"modified parameters optimization algorithms" » "modified parameter optimization algorithms", "modified parameter estimation algorithms", "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameters estimation algorithm"
"modified adaptive convolution algorithms" » "modified adaptive evolution algorithm", "modified adaptive solution algorithm", "modified adaptive construction algorithms", "modified adaptive ventilation algorithms", "modified passive 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 parameters optimization algorithms") or ("modified adaptive convolution algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameters optimization algorithms") OR ("modified adaptive convolution algorithms")).
• Removing quotes may allow a broader search: (( modified parameters optimization algorithms ) or ( modified adaptive convolution algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameters optimization algorithms") or ("modified adaptive convolution algorithms"))*.
