Perhaps you should try some spelling variations:
"modified location optimisation algorithm" » "modified location optimization algorithms", "modified location estimation algorithm", "modified location estimation algorithms", "modified allocation optimization algorithm", "modified carbon optimisation 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"

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 optimisation algorithm") OR ("modified learning method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified location optimisation algorithm\") OR (\"modified learning method algorithm\"))".
• Removing quotes may allow a broader search: (( modified location optimisation algorithm ) OR ( modified learning method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified location optimisation algorithm") OR ("modified learning method algorithm"))*.
