Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"model using one algorithm" » "model using our algorithm", "model using _ algorithm", "model using mom algorithm", "code using one algorithm", "models nursing one algorithm", "powder using one algorithm", "model using open algorithm", "model using pre algorithm", "model using online algorithm"

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