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