Perhaps you should try some spelling variations:
"modified parameter optimization algorithm" » "modified parameter optimization algorithms", "modified parameter optimisation algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithm"
"modified traces evolution algorithm" » "modified traces solution algorithm", "modified traces evolutionary algorithm", "modified traces convolution algorithms", "modified sales evolution algorithm", "modified time evolution algorithm"

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

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