Perhaps you should try some spelling variations:
"modified allocation optimization algorithm" » "modified allocation optimization algorithms", "modified allocation optimisation algorithm", "modified allocation estimation algorithm", "modified location optimization algorithm"
"modified carbon optimized algorithms" » "modified carbon optimized algorithm", "modified carbon optimizer algorithms", "modified carbon optimization algorithms"

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