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 source algorithm" » "machines using our algorithm", "machines using search algorithm", "machinery using source algorithm", "machines using force algorithm", "machines using morse algorithm"

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

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