Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"modified location optimizer algorithms" » "modified location optimized algorithms", "modified location optimized algorithm", "modified location optimization algorithms", "modified carbon optimizer 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 multiobjective estimation algorithm") or ("modified location optimizer algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective estimation algorithm") OR ("modified location optimizer algorithms")).
• Removing quotes may allow a broader search: (( modified multiobjective estimation algorithm ) or ( modified location optimizer algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective estimation algorithm") or ("modified location optimizer algorithms"))*.
