Perhaps you should try some spelling variations:
"modified carbon optimisation algorithms" » "modified carbon optimization algorithms", "modified carbon estimation algorithms", "modified carbon estimation algorithm", "modified carbon optimization algorithmss", "modified carbon estimation algorithmss"
"modified parameter optimisation algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameter optimization algorithms", "modified parameter estimation 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 parameter optimisation algorithm") OR ("modified carbon optimisation algorithms"))~.
• Removing quotes may allow a broader search: (( modified parameter optimisation algorithm ) or ( modified carbon optimisation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameter optimisation algorithm") or ("modified carbon optimisation algorithms"))*.
