Perhaps you should try some spelling variations:
"modified multiobjective optimizer algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithms", "modified multiobjective optimized algorithm"
"model using real algorithm" » "model using adam algorithm", "model using search algorithm", "code using real algorithm", "models nursing real algorithm", "powder using real algorithm", "model using metal algorithm", "model using raw 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 real algorithm") or ("modified multiobjective optimizer algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("model using real algorithm") OR ("modified multiobjective optimizer algorithms")).
• Removing quotes may allow a broader search: (( model using real algorithm ) or ( modified multiobjective optimizer algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("model using real algorithm") or ("modified multiobjective optimizer algorithms"))*.
