Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"model using methods algorithm" » "model nursing methods algorithm", "model making methods algorithm", "model counting methods algorithm", "code using methods algorithm", "models nursing methods algorithm", "powder using methods algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("model using methods algorithm") or ("modified multiobjective optimized algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("model using methods algorithm") OR ("modified multiobjective optimized algorithm"))*.
• Removing quotes may allow a broader search: (( model using methods algorithm ) or ( modified multiobjective optimized algorithm ))*.
