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"
"modified learning method algorithm" » "mobile learning method algorithm", "modified caging method algorithm", "modified learning mom algorithm", "modified learning methods algorithm", "modified graining methods algorithm", "modified learning emotion 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: (("modified location optimization algorithm") or ("modified learning method algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified location optimization algorithm") OR ("modified learning method algorithm")).
• Removing quotes may allow a broader search: (( modified location optimization algorithm ) or ( modified learning method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified location optimization algorithm") or ("modified learning method algorithm"))*.
