Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"modified multiobjective source algorithm" » "modified multiobjective lot algorithm", "modified multiobjective our algorithm", "modified multiobjective search algorithm"

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 multiobjective source algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective estimation algorithm") OR ("modified multiobjective source algorithm"))*.
• Removing quotes may allow a broader search: (( modified multiobjective estimation algorithm ) or ( modified multiobjective source algorithm ))*.
