Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"machinery using ph algorithm" » "machines using ph algorithm", "machinery using _ algorithm", "machinery using mppt algorithm", "machinery using qspr algorithm", "machinery using pre algorithm", "machinery using a algorithm"

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

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