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 raw algorithm" » "machinery using raw algorithm", "machines using adam algorithm", "machines using _ algorithm", "machines using mom algorithm", "machines using real algorithm", "machines using a algorithm", "machines using low algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("machines using raw algorithm") or ("modified multiobjective optimized algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("machines using raw algorithm") OR ("modified multiobjective optimized algorithm")).
• Removing quotes may allow a broader search: (( machines using raw algorithm ) or ( modified multiobjective optimized algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("machines using raw algorithm") or ("modified multiobjective optimized algorithm"))*.
