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