Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"machines counting methods algorithm" » "machines using methods algorithm", "machines nursing methods algorithm", "machines control methods 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 counting methods algorithm") or ("modified multiobjective optimized algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("machines counting methods algorithm") OR ("modified multiobjective optimized algorithms"))*.
• Removing quotes may allow a broader search: (( machines counting methods algorithm ) or ( modified multiobjective optimized algorithms ))*.
