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 metal algorithm" » "code using metal algorithm", "models nursing metal algorithm", "powder using metal algorithm", "model using real algorithm", "model nursing mental algorithm", "model using medical algorithm"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"model using metal algorithm\") OR (\"modified multiobjective optimized algorithms\"))~".
• Removing quotes may allow a broader search: (( model using metal algorithm ) OR ( modified multiobjective optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("model using metal algorithm") OR ("modified multiobjective optimized algorithms"))*.
