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 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"

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