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