Perhaps you should try some spelling variations:
"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"
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimisation algorithm", "modified objective estimation algorithm", "modified objective estimation algorithms"

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

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