Perhaps you should try some spelling variations:
"modified objective evolutionary algorithm" » "modified objective evolution algorithm", "modified objective solution algorithm"
"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"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified objective evolutionary algorithm") OR ("modified location optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective evolutionary algorithm\") OR (\"modified location optimization algorithm\"))".
• Removing quotes may allow a broader search: (( modified objective evolutionary algorithm ) OR ( modified location optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective evolutionary algorithm") OR ("modified location optimization algorithm"))*.
