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