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 search algorithm" » "model using source algorithm", "model using egarch algorithm", "model nursing research algorithm", "model using servo algorithm", "code using search algorithm", "models nursing search algorithm", "powder using search 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 search algorithm") OR ("modified multiobjective optimizer algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"model using search algorithm\") OR (\"modified multiobjective optimizer algorithms\"))".
• Removing quotes may allow a broader search: (( model using search algorithm ) OR ( modified multiobjective optimizer algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("model using search algorithm") OR ("modified multiobjective optimizer algorithms"))*.
