Perhaps you should try some spelling variations:
"modified orca solution algorithm" » "modified orca evolution algorithm", "modified orca convolution algorithms", "modified orca evolutionary algorithm", "modified norway solution algorithm", "modified drug solution algorithm", "modified nacl solution algorithm"
"modified objective solution algorithm" » "modified objective evolution algorithm", "modified objective convolution algorithms", "modified objective evolutionary algorithm", "modified objective allocation 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 orca solution algorithm") OR ("modified objective solution algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified orca solution algorithm\") OR (\"modified objective solution algorithm\"))".
• Removing quotes may allow a broader search: (( modified orca solution algorithm ) OR ( modified objective solution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified orca solution algorithm") OR ("modified objective solution algorithm"))*.
