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 trained solution algorithm" » "modified trained evolution algorithm", "modified trained convolution algorithms", "modified trained evolutionary algorithm", "modified traces solution algorithm", "modified saline solution algorithm"

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

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