Perhaps you should try some spelling variations:
"modified location optimization algorithm" » "modified location optimization algorithms", "modified location optimisation algorithm", "modified location estimation algorithm", "modified allocation optimization algorithm", "modified static optimization algorithm", "modified carbon optimization algorithm"
"machinery using method algorithm" » "machinery using mom algorithm", "machines using method algorithm", "machinery nursing methods algorithm", "machinery focusing method algorithm", "machinery using metal 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: (("machinery using method algorithm") or ("modified location optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("machinery using method algorithm") OR ("modified location optimization algorithm")).
• Removing quotes may allow a broader search: (( machinery using method algorithm ) or ( modified location optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("machinery using method algorithm") or ("modified location optimization algorithm"))*.
