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

Try widening your search to All Fields.

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

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