Perhaps you should try some spelling variations:
"modified parameters optimization algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimisation algorithm", "modified parameters estimation algorithm", "modified parameters estimation algorithms"
"modified carbon optimization algorithms" » "modified carbon optimisation algorithm", "modified carbon estimation algorithms", "modified carbon estimation algorithm", "modified carbon optimisation algorithms", "modified carbon estimation algorithmss", "modified market optimization algorithms"

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 parameters optimization algorithm") OR ("modified carbon optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified parameters optimization algorithm ) or ( modified carbon optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameters optimization algorithm") or ("modified carbon optimization algorithms"))*.
