Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"machines using real algorithm" » "machinery using real algorithm", "machines using adam algorithm", "machines using search algorithm", "machines using metal algorithm", "machines using raw 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: "((\"machines using real algorithm\") OR (\"modified multiobjective optimized algorithms\"))~".
• Removing quotes may allow a broader search: (( machines using real algorithm ) OR ( modified multiobjective optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("machines using real algorithm") OR ("modified multiobjective optimized algorithms"))*.
