Perhaps you should try some spelling variations:
"modified multiobjective optimizer algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithms", "modified multiobjective optimized algorithm"
"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"

Try widening your search to All Fields.

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 one algorithm") or ("modified multiobjective optimizer algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("machines using one algorithm") OR ("modified multiobjective optimizer algorithms")).
• Removing quotes may allow a broader search: (( machines using one algorithm ) or ( modified multiobjective optimizer algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("machines using one algorithm") or ("modified multiobjective optimizer algorithms"))*.
