Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"machines using one algorithm" » "machinery using one algorithm", "machines using our algorithm", "machines using _ algorithm", "machines using mom algorithm", "machines using open algorithm", "machines using pre algorithm", "machines using online 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 one algorithm\") OR (\"modified multiobjective optimized algorithm\"))~".
• Removing quotes may allow a broader search: (( machines using one algorithm ) OR ( modified multiobjective optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("machines using one algorithm") OR ("modified multiobjective optimized algorithm"))*.
