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 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.

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